Taylor Premium Thermex Pro Picks offer the most traditional style and feel from the Taylor DarkTone Series. Made with a proprietary thermoplastic formulated to resemble authentic tortoiseshell, these picks glide smoothly off each guitar string for a warmer, richer response with less twang. Taylor Thermex picks are available in 351, 346 and 651 shapes and are precision cut in a 1.5mm size. Made in the USA.
