This is ultra-thin, white Teflon tape which will seal the sides of your reed when one or two wrappings are applied. It sticks to itself, and is easier to use than fishkin.
Vegetarians and vegans can comfortably use this non-animal product instead of traditional fishskin, which is an animal based substance. Another excellent alternative is Parafilm tape, also vegan friendly.
This roll will seal hundreds and hundreds of leaky reeds. It measures a vast 260″x 1/2″.
