Fred Kelly Delrin Medium / Large Gauge Slick Picks. 2 picks in each pack. Colors shipped will vary. Fred Kelly's Slick Pick has a flat pick point that enhances smooth strumming. This pick is neither big nor bulky, like many on the market, and is the first pick that acts like a straight pick. Delrin is an extremely strong, unbreakable material, and provides a very soft and natural sound on the strings.
