### ⭐⭐⭐⭐⭐ Not just for labs!
*by H***N on June 2, 2017*

I have several sets of these and use them for a lot of stuff, none in a science lab or classroom. Unless you count my kitchen as a science lab. They (with cork stoppers) currently hold water, taco sauce from a taco kit, and homemade salad dressing in the fridge, M&Ms, peanuts and almonds on my counter, and flowers in my living room. The tiny one makes a really cute bud vase. With my soapstone countertop and these and beakers holding various foods, I guess I do kind of have a Breaking Bad kitchen! These are good quality and fun to have around.
