Lessons in Chemistry Model Kit - Old Nobby 239 Pc Molecular Set Organic Chemistry for Students - Complete Molecular Model Kit for STEM, Visualizing Atoms, Bonds and Structures (Pack of 2)

If you will imagine a formular you need this tool. No doubt.!!

Good kit for organic class. Easy to build and take apart models. Can be used to built reasonably sized molecules. Holding up well so far. Can make space filling models or indicate double and triple bonds with flexible sticks.

My son uses this for his organic chemistry class. He says it’s been extremely helpful while studying. It’s easy to use and has enough pieces for what he needs.

I was pleasantly surprised to find this product. My Biology and AP Chem students build models to help them understand organic structure, functional groups, dehydration synthesis, polymers and other things. The tiny, cheap model kits are very hard for them to manipulate, and larger model sets are wayyyy too expensive or hard to assemble. This one is large enough for them to easily build and manipulate the models, but small enough to store easily. The best part is that the atoms & bonds are easy to assemble & take apart, and are durable enough to stay together. Quite affordable, too. Very nicely done. The packaging and plastic box looks cool, but it immediately becomes clear that you'll need a larger container, one that latches. The kits would soon become hopelessly scattered without a better box. I found 12" Husky storage boxes at Home Depot (with adjustable dividers) for about six bucks that work well. But...that frustratingly adds to the cost of the kit.

Exactly what I expected. Good product

Great product- we ordered multiple sets to build longer FNA modules and phospholipids and such. It was such a hit that we bought a set for the high school science class.

I am taking Orgo 1 now and this kit is perfect. My professor has us use it to model structures in class and even on exams. My friends with slightly cheaper kits have had some trouble, but this is kind of the right balance between sturdy and not-too-expensive. Highly recommend. It also comes with a stencil for organic chemistry shapes which I didn't realize and is really nice. All of the bits also have resealable plastic bags which is helping me keep it organized. The lid of the box doesn't stay on without rubber bands though which makes it a bit of a hassle to carry around.

This kit is perfect for learning molecular geometry and for helping with chair flips in organic chemistry as well.

Good quality and correct bonds, a good started kit. My son loves it.

Great molecular kit! Helped me a lot when I took ochem! This helps A LOT with drawing molecular structures with the right stoichiometry. Had this for a few months, and nothing broke; everything's still in excellent condition. There are even some very useful stencils, which I think is a great addition and saves time during the exams or if you're doing some ochem coursework under pressure! Highly recommend!

Received the product in good condition. The quality is as expected. But the delivery is much delayed and reached 2 weeks after promised delivery date.

El producto llegó antes de la fecha, buen servicio. El material del producto es firme, limpio y Buenos acabados. Excelente producto.

My kids love to play with it. The bonds fit perfectly, hold well, and are very easy to take apart. There is also a small tool to help taking atoms apart, helpful especially when using short bonds. The only downside of this kit, that there is not enough atoms, about 100, so not enough to make very complex molecules, or to make many molecules at once, the kids had hard time to play together, but the price seemed to be fair, so I bough additional two boxes. Now all the kids are happy.
