Dunlop Tortex - Guitar Pick / Plectrum – Red 0.5mm - 1 2 3 6 12 20 50. These Dunlop Tortex series picks are the mutt's doo-dahs, and picks that seriously kick bottom. Bonus Factoid Before We Need A Wee Lie Down : Jim Dunlop created the plastic known as Tortex to replace tortoiseshell guitar picks - since an international ban on tortoiseshell in the 1970s restricted the sale of one of the best guitar pick materials used around the world.
