I don't use picks of this size for electric guitars, but they work quite well on bass. Grip and durability aren't the best, but not bad at all. Now, the metal box that these come in with is actually very useful to keep your picks in. You can even keep it in your case, if you're a gigging musician.
These are indeed very standard picks in all terms, but come in a handy packaging box.
This picks I'm using in my electric guitar and also acoustic. They have a nice slow attack, not good for some heavy stuff, but good for strumming, lite picking (even this picks are hard), bluesy, djazzy stuff etc. Not for a math people, I guess. But still... almost for everything, especially if you need the sound with a smooth attack.
