Caps break easily and quickly [SEP] If the caps were sturdier, these would be a great product. Mostly I use them for small amounts of face foundation kept in a drawer.  After opening them about 15 times, the cap cracks.  I'm now trying to put the cap on loosely so it's easier to remove without too much pressure.  I have some older ones of another brand that have held up for years - next time I'll look for those to buy.
