'Thin felt' ukulele plectrums, triangular picks, feltrums x6 (UK seller)

This is a set of 6 'new design' ukulele plectrums. They are strong and flexible, but only 1mm thick, much thinner than most felt plectrums (which are around 3 to 4mm in thickness). The surface of the plectrum has a smooth 'velvet' texture.
