Glass guitar picks may be harder and heavier than their metal or plastic counterparts, but they also produce a greater range of tone. My glass guitar picks are completely handcrafted to make great music and last a lifetime. This piece features a combination of a tan-colored glass base and blue-green fritted glass. It measures approximately 1'' x 1'', and is made of pure borosilicate, one of the most durable types of glass. If you like this design in a different set of colors, kindly message me so that I can accommodate your request. As with my other glass creations, this piece is kiln-annealed in my studio.
