I've tried and used many condiment containers over the years and they all let me down within a year or two of common use.
This is the best I've seen.
The tops secure into the holes so it literally CAN'T spill
Initially I was concerned about how secure the base would be and how easily it could pull off accidentally.
Having tried to (accidentally on purpose) catch it on things and pull it off I can say it is actually much more secure than I thought
It is a simple no frills functional product that does its job without fuss or hassle
Impressed enough that next day I went back, there were three left and I bought all three
