The stones are a nice size. The masker holder keeps my mask close when I take it off to eat when I am at work. I don’t have to worry about where to keep it while I’m eating lunch. The clasps slide easily on the straps of disposable masks. No so for the washable, reusable masks. I have had to stuff or fold the straps on the reusable masks to get them in the clasps. All in all the holder is pretty as well as functional.
