Good fit. Helps keep my vials sealed and sanitary. Clean before and during each use to prevent issues. The large caps are a great fit on 10ml water vials and the small caps are a great fit on 3ml research vials. The price was good, the variety of size and color are nice. Overall no complaints to report.

Great for the price

They are very nice quality, but the 3ml are a little tight on the vial. This is not necessarily a bad thing, but something to note. The 10ml are a little lose on 10ml, but work great on 30ml hospira bac water
