WEHSIDAScience Keychains Set of 2 Chemical Keychains Serotonin and Dopamine Key rings Neurotransmitter Keychains Molecule Keychains Periodic Table

These showed up on time, in tact, and they're actually pretty cute! They seem a little delicate, but I keep a good number of keys on this ring and the charm hasn't broken off yet. I gave the other one away as a gift, and all in all this was a great purchase!

This is super cute, and it holds up against abuse (im kind of rough with my keys). Good purchase.

My science teacher friends liked them. However, the “molecule” can easily break off from the earring. One of them was already broken when I opened the package.

Very cheaply made, do not buy

Kinda cheap still cool

They look exactly like how displayed in the picture, and a great gift for anyone! I was really happy with this product and I was also super happy because when it shipped to me there was also another little keychain in the package which was so cute.

It was shipped very fast and the vender is very helpful. Loved the product, it’s a gift for someone special, it’s perfect! Hardly recommend the product and the vendor

Cheaply made. One keychain broke within 2 hours, I suspect the other will break too. Don’t buy it.
