This Pack of 3 Artist Quality Moroccan Argan Sculpted Guitar Picks is recommended for acoustic and acoustic electric guitar. These picks are a finely sculpted artisan crafted guitar pick with a thumb impression and finger groove designed to be the most comfortable pick grip of your life. Our Moroccan Argan is a beautiful and warm grain wood that wears in nicely and allows for a flowing magical tone when played on most acoustic and acoustic electric instruments. US Blues® offers music accessories made of sustainably sourced exotic materials that improve the tone and modulation of your instrument and therefore your overall playing and enjoyment. We use by-products of various industries, such as guitar making, to source materials that otherwise would not have been repurposed. We strive to bring the quality of your music to a new higher level and are proud to have elevated the guitar pick to the level of "Pick as Instrument".
