Sister Mintaka presents the Fray Check by Prym.
Fray stop is a colourless liquid that prevents stressed areas; such as button holes, seams, shirt collars, and cuffs; from fraying by reinforcing the fibres.
22.5 ml of fray stop are included in the dosing bottle with the pipette-like opening. Only after multiple washes can the effect of the fibre-reinforcing liquid can lightly subside. This treatment can be repeated as often as desired.
