I usually play very hard on my steel stringed guitar with this plectrum and it appears to not recieve any chips from my playing. I am impressed with the material and it's an obvious choice if I ever need to purchase a plectrum again.
The sound is better with horn than with plastic, against the strings.
With this horn plectrum:
The strumming feels more comfortable and sounds not so floppy or "picky", (plastic is too hard and creates a mean "tapping" sound, horn is more soften and sounds natural against the strings.)
The colour looks nice, and it has a beautiful visual appearance.
The grip in the hand is comfortable since It's quite large, not easily dropped. It's a bit shiny but that looks nice and the colours looks cool when being illuminated by light.
I'll definitely stick with this plectrum for several decades.
