Cost less than $1 to make. - Loved them! Less than $1 to make each of these cute favors! Will be adding some ribbon and labels for the finishing touches. 1. 25 plastic test tubes ($10.99) 2. Nestle rich milk chocolate hot cocoa mix 27.7 oz from Target ($5) 3. Great Value Chocolate Sprinkles from Walmart 10.5 oz but I only used less than 3oz. ($3.25) 4. Jet-puffed Mallow Bits 3 oz from Target ($1.59) WHAT I DID: Put approximately 2.5 tbsp of hot chocolate mix using a small funnel. Place lid back on and tap the tube on a hard surface to allow the mix to condense. You’d be surprise how much it goes down! Add another 0.5 tbsp of hot chocolate mix as needed until your mix reaches about 3/4 inch below the bottom-most line. Use clean Gloves to wipe off the powdery surfaces Along the walls of the tube above the hot chocolate mix. Add 0.5 tsp of chocolate sprinkles. Fill the rest with the Jet-puffed mallow bits. Screw on lid. Leave completrd tubes standing upright in cups. Instructions for your guests: Pour out contents of tube and combine with 1 cup of hot water. Stir until fully dissolved. Enjoy! With this recipe, I ended using almost all of the nestle hot chocolate (27.7 oz) in all 25 test tubes except for about 4 tablespoons - enough to enjoy a cup for myself. Very happy with the quality of the tubes. Only one lid came slightly dented. Review: Great - I made hot chocolate favors for a baby shower with these. They were beautiful and everyone loved them! There were no issues with spills, cracks or leaks. ## Features - Package includes 18 clear plastic test tubes,1 cleaning test tube brush. - Flat test tube is made of high quality PET plastic,durable and not easy to break,safe and eco-friendly. - Test tube with screw cap is 15cm/6inch in height,inner diameter is 22mm,outer diameter is 25mm.Capacity of clear test tube is 115ml,cleaning brush is 20cm/7.9inch in length. - Our flat tube with screw cap has a great seal for storage,with flat bottom design,you can place them on any flat surface. - Test tube with large capacity has wide uasge,you can even put some plants in it to decorate your wall or bedroom,also perfect for bath salt,candy,beans or grains storage,special DIY crafts for science party favors. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 1,179 Reviews | ## Images ![18 PCS 115ml Clear Plastic Test Tubes,Flat Test Tube,Plastic Test Tube with Screw Caps and 1 Cleaning Brush for Bath Salt,Candy Storage,Science Party Favors,Wedding Decor - Image 1](https://m.media-amazon.com/images/I/81KtZN36ooL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the outside width at the base?

They were beautiful and everyone loved them! There were no issues with spills, cracks or leaks. ### ⭐⭐⭐⭐⭐ Great for Instant drink mixes *by F***R on May 21, 2025* Great size…I bought them to make Christmas instant hot cocoa mix gifts (recipe online) with mix, chocolate chips and tiny marshmallows, but actually use them to pre-make instant coffee with stevia and creamer for a quick dump into a travel mug. The lids are secure and quality of the tubes is perfect. ## Frequently Bought Together - 18 PCS 115ml Clear Plastic Test Tubes,Flat Test Tube,Plastic Test Tube with Screw Caps and 1 Cleaning Brush for Bath Salt,Candy Storage,Science Party Favors,Wedding Decor - Augshy Microphone Covers Foam,20 Pack Thick Handheld Stage Microphone Windscreen Microphone Cover Foam Karaoke DJ Microphone Covers Disposable(10 Color) - Yiasangly Microphone Cover, Thick Colorful Foam Mic Cover, Handheld Stage Microphone Windscreen, Reusable Foam Covers， Foam Micro Filter for Most Handheld Microphone for Karaoke DJ - 10 Pieces --- ## 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/278566942-18-pcs-115ml-clear-plastic-test-tubes-flat-test-tube](https://www.desertcart.pt/products/278566942-18-pcs-115ml-clear-plastic-test-tubes-flat-test-tube) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-16*
