Swpeet 252 Pcs Molecular Model Kit for Inorganic & Organic Molecular Model Teacher and Student Kit - 86 Atoms & 153 Links & 12 Orbitals & 1 Short Link Remover Tool

Got me through my second year organic chemistry class in university. However, by the end of the semester, some of the pieces became so loose to the point where the model was falling apart as you were building it. Not enough carbons provided in my opnion.

Here is Thymine (half rung) and part of the DNA backbone built from these. I agree with the other comments, box could use a latch of sorts, but the suggestions of elastic bands or gallon ziplocks (or both) are great suggestions. I found the quality great. The bonds work reliably, hold well and aren't loose or too difficult. As soon as I got it, I made benzene (with double bonds alternating), N2 (triple bond) and a whole host of other things including nitric and sulfuric acids. I'm seriously considering getting more kits.

Love it. Very helpful to use for visualizing isomers etc.—was allowed to use during my OCHEM exams. Do not buy if you need to make more than 1 or 2 molecules. You can make a disaccharide but nothing super big—mostly used for configuration visulization and molecular geometry.

This is super helpful if your in o-chem or even gen-chem. I would recommend getting on with a few more connectors and molecule options. But great quality!

As a biochemistry major, this kit has everything you'll need! I would recommend this for organic chemistry especially when learning Newman Projections. It offers a lot of educational value, is easy to use and assemble, and functions well for its purpose.
