Have ordered these plastic test tubes multiple times to use as a water reservoir in the wood craft vases we turn. Allows the vase to be used for live as well as dry flowers. These vases are a big seller at craft shows.

Got these to fill with tea samples. Perfect size!!

I used these to make bath salts and they were a huge hit! Everyone loved them!

I love giving the to my workshop participants filled with link salt. Love them!

This product was poorly packed and of a very cheap quality! Bought them in hopes of using them for propagating plants. But they won’t hold water because most are cracked.

I did not read the description did not realize how small I am an ant keeper so the comfort of my ants is one of my top priorities it was very small so I am not sure if it will comfortly hold my larger ant queens

I have needed these for a specific project, and when I got them, 3 of them came with corks that were way too big!
