Prym Fraycheck 22.5ml
A colourless liquid that permanently strengthens & binds fabric surfaces, preventing textile edges from fraying. Use on buttonholes before you cut them open or on laddered tights to stop the ladder from growing. Be sure to remove any chalk or erasable pen marks before adding Fraycheck or you’ll lock them in forever. Ensure good ventilation & don’t breathe in the chemical fumes.
