Jingzan 136 Pieces Organic Chemistry Model Kit, Chemistry Molecular Model Kit Set for Student or Teacher - 59 Atoms & 76 Bonds & 1 Short Link Remover Tool - Science Toys

Everything came as shown in the image; this is the cheapest kit i found for this many pieces. for building molecular structures as it comes with different elements and two types of carbon (1 with 3 bonds and 1 with 4 bond holes).

The pieces are great for my OChem class, the snaps are a little hard to place in and out but it works great for what I needed

Delivered just in time for my sons first organic chemistry homework assignment. Awesome tool to visualize complex material.

Sturdy, easy to take apart and put together, enough materials for basic structures.

I'd say this is okay for the cost. The sheet on the box lists a 3 hole 120 degree angle atom as a carbon and a 4 hole 109 degree angle as a carbon. It lists a 5 hole atom as a phosphorus and a six hole atom as a sulfur. This kit would not be good to use if you're using the sheet to learn about atoms, but for any type of chem student thay knows bond angles and geometry and such, these will do the job. You only get 12 carbon atoms so you won't be building anything too fancy.

Perfect for kids

If you want a set for just one semester I recommend this because it works for enough time for one semester, but then my pieces started to break. If you’re going to be in chem for longer than a semester I recommend spending more money on a nicer version.

half of the carbons came without the correct connecting spots. also, how the model fits together is not correct for visualization.
