Review (5/5): Excellent Bottles for Certain Hobbies
These bottles are perfect for storing, and even displaying, small items like sand, beads, soil, etc. They are crystal clear so that the inside material can be seen perfectly, and they seal well. I have never overtightened the caps, so I do not know whether or not they would split, but they seem very strong. When I stored a water sample in one, it did not leak during its very long trip home. I highly recommend these bottles!
