Review: Great kit to help with chemistry - I bought this for my high school aged daughter who is in AP Chemistry. She uses chemistry model kits in class to help with learning, and finds it so helpful she wanted one of her own. She knows she will get a lot of use with it for school work now and in the future as she wants to study chemistry in college. She also just likes to play with it haha. The pieces are constructed very nicely and fit together perfectly. There's even a little tool piece to help take the pieces apart which is handy. Everything is of excellent quality. HOWEVER, I will agree with all of the other reviewers who commented on the box not being big enough to hold all the pieces and close properly. This is 100% true. It's so odd how they are even trying to get all of these pieces into this box. I don't even think the box will stay closed well with it being empty! Such a strange design. We are buying another latching container to put this in. I'm still happy with the kit, but just know you'll need another storage solution. ## Features - Comprehensive Chemistry Kit: This chemistry molecular model kit includes 239 pieces with color-coded atoms and flexible bonds; helps students and teachers easily visualize complex structures - Portable and Organized: A durable compact case keeps this chemistry set neatly stored and travel-ready; ideal for students, teachers, or professionals who need an organized tool for learning anywhere - Built to Last: Made from strong, dependable materials; this molecule modeling kit is designed for repeated classroom, lab, or self-study use; provides lasting value for learners at any level - Quick Easy Assembly: User-friendly design makes this molecule building kit simple to put together and disassemble; explore bonding configurations efficiently without wasted time or frustration - Engaging Hands-On Learning: This chemistry model kit bridges theory and practice; enhances understanding of organic and inorganic chemistry concepts through interactive, visual demonstrations ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NCU854K | | Age Range Description | Adult, Kid | | Best Sellers Rank | #15,006 in Toys & Games ( See Top 100 in Toys & Games ) #143 in Educational Science Kits | | Brand Name | Old Nobby | | Customer Reviews | 4.7 out of 5 stars 6,966 Reviews | | Educational Objective | STEM | | Included Components | Atoms, Bonds, Bond Remover Tool, Instructional Guide, Bonus Molecule Stencil | | Item Dimensions | 12.4 x 8.6 x 2.4 inches | | Item Type Name | Molecular Chemistry Kit | | Item Weight | 680 g | | Manufacturer | Old Nobby | | Manufacturer Maximum Age (MONTHS) | 360 | | Manufacturer Minimum Age (MONTHS) | 180 | | Manufacturer Part Number | ZY-ghm-0902-42 | | Material Type | Plastic | | Model Number | ZY-ghm-0902-42 | | Number of Items | 1 | | Number of Packs | 1 | | Set Name | Old Nobby Chemistry Set | | Size | 239-Piece Kit | | Theme | chemistry | | Unit Count | 1 Count | ## Images ![Organic Chemistry Molecular Model Kit - 239 Pieces - Image 1](https://m.media-amazon.com/images/I/71tqhf3yX1L.jpg) ![Organic Chemistry Molecular Model Kit - 239 Pieces - Image 2](https://m.media-amazon.com/images/I/716pmkgM3LL.jpg) ![Organic Chemistry Molecular Model Kit - 239 Pieces - Image 3](https://m.media-amazon.com/images/I/71wJD5XzrVL.jpg) ![Organic Chemistry Molecular Model Kit - 239 Pieces - Image 4](https://m.media-amazon.com/images/I/71QHcN3P4NL.jpg) ![Organic Chemistry Molecular Model Kit - 239 Pieces - Image 5](https://m.media-amazon.com/images/I/71oMpRMuF9L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Does it come with some nitrogen blue holes 3 at 120 degree instead of 107 degree? carbon black holes 3 and 2, oxygen red holes 1 also helpful.** A: It sounds like you are interested in geometries of C, N, and O compounds which involve double and triple bonds and this means atoms that are trigonal planar (120 degree holes) and linear (180 degree holes). This kit does not have such atoms ( I don't know any kits that do) but does have trigonal bipyramid atoms (5 holes) that can be used for trigonal planar geometries and octahedral atoms (6 holes) that can be used for linear geometries. Be aware that few molecules actually have 120 degree bond angles owing to different electron pair repulsions of the various bonds and lone pairs. Therefore, rather than using the 5 hole atom for trigonal planar geometries of C and N, I think you are better off using the kit's existing C, N, and O atoms for bonding situations where these atoms have trigonal planar or linear geometries and using the long, flexible bonds to represent the double and triple bonds that are involved. This gives reasonable structures and clearly highlights the double and triple bonds. In my opinion, all model kits would be improved if the C, N, and O atoms were all tetrahedral (4 holes) so you could also include lone pairs of electrons in your model. Seeing these lone pairs is important to understanding the molecular geometry of molecules containing nitrogen and oxygen and more than compensates for larger errors in the bond angles. Another improvement for this kit would be to remove all but two of the 5-hole and 6-hole atoms (rarely needed) and increase the number of carbon and hydrogen atoms. **Q: Are the bonds flexible enough for representing chair configurations?** A: If you are referring to chair and boat configurations of cyclohexane the answer is yes since no bond flex is really required. If some flex is required for a particular molecule you have in mind you could use the longer flexible bonds to construct your model. It won't be beautiful but it will probably give an acceptable structure. **Q: Are the bonds easy to remove and put on? I have the molymod version and they require a lot of strength to put on and remove. Bummer.** A: Yeah super easy to put together and for the little short bonds that might be hard to grab there is a tool that comes with it to help pull them apart. **Q: Can this model make fisher projections?** A: Hi there S.M, There is an excellent youtube video that explains how to use the Molecular Kit with Fisher projections. It only goes for 2 minutes and sums it really well https://www.youtube.com/watch?v=tTc19BDXVG8 Anything else or how we can help, please let us know Regards Peter ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good basic kit for organic chemistry class *by R***T on December 9, 2025* Good kit for organic class.

It is so much better than the set that was recommended to me in my syllabus, which was more expensive and somehow was more cheaply made. The set that was recommended to me was cold, boring, and made the subject even scarier. It was so hard to use that many students never used it. The Old Nobby kit? It’s incredibly intuitive to use, fun, and takes the fear away from organic chemistry immediately. As you go through your textbook you’ll say “Oh I can’t wait to build this!” Buy this set. The first time you build cyclohexane or benzene, the first time you perform a chair flip, the first time you build acetylene, the first time you build ethylene and see how everything comes into the same plane, organic chemistry suddenly CLICKS. For a class as challenging as orgo, you can’t put a price on something like this. ## Frequently Bought Together - OLD NOBBY Organic Chemistry 239 Piece Model Kit - Molecular Model Kit with Atoms, Bonds, Instructional Guide, Bond Removal Tool, and Bonus Molecular Stencil - Organic Chemistry Reactions QuickStudy Laminated Reference Guide (QuickStudy Academic) - Organic Chemistry as a Second Language: First Semester Topics --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/655936578-organic-chemistry-molecular-model-kit-239-pieces](https://www.desertcart.pt/products/655936578-organic-chemistry-molecular-model-kit-239-pieces) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-24*
