When the pick feels too tight or loose around your thumb, simply expand or contract the thumb pick’s wrap for the best fit. Adjustments are made quickly and easily without heat or tools. Spoon shaped striking surface for more volume and non-metallic tone. With Nickel-silver construction, players can match tone of finger picks. Choose orientation and size.
