Very worthwhile purchase, premium quality plectrums that don't hinder tone or ability to play, at least in my case.
If you're looking for good quality jazz picks, I wouldn't look any further.
However, if you do not already use jazz picks, it takes some getting used to as they are quite a bit smaller than standard ones, and some people complain that they slip out of their hands - that's why I didn't give five stars for grip, some of the Dunlop jazz picks have grip indents that take away this problem but they are not as comfortable in my opinion.
