The picks themselves are good, although they could be a bit more grippier. They are matte finnish but tend to smooth out if used longer and I found to drop them more frequently if I use them for a long time and my hands get sweaty.
They are 1.14 mm thick which falls right in the category that can be used for guitar and bass (which I rarely play with a pick but if needed I know I have the tool for the job).
If those are too thick for your taste I think they come at .80mm as well.
They are what they are, picks, they doo the job, they do it well and look cool while doing it. Like I said-the could be a bit grippier but that is a minor thing.
This is my second order of those picks, first one being the ones that come in a tin box. I ended oup loosing some (like I always do) giving some away, and ended up with only two left (out of six that you get in the package)
