Customizable acrylic guitar picks slip onto your fingers and act like fingernail extensions for precision picking. Small, medium, large, and extra large sizes available. Brilliant design slides on over your finger, but the picking edge fits underneath your fingernail! You still have the intimate string touch you get with your own nails, but with no danger of painful nail breaks. Space age clear acrylic material can be "manicured" to precise length. Slide 'em on, and wail without fear! Small - (children, petite women), medium - (women, smaller men), large - (average to large men), or extra large - (very big fingers, thumbs).
