Worth it!
Exactly as described, fits 2 sizes of vial. Love the different colors, easy to use and keep my vials clean and safe in between uses. Totally worth the price!

Excellent solution to prevent vial contamination.
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.
