Blu-Tack is the original light blue reusable adhesive. Blu Tack is a offers a clean, safe and a simple alternative to tapes and pins. Itis the perfect modelling material with excellent moulding qualities because it resists slump, will not shrink, dry out or harden and can be used over and over again. It has excellent adhesive qualities so can be used to create 3 dimensional models and 2 dimensional images to decorate windows or walls. Main uses for Blu tack are to stick posters, banners, photos, borders, signs etc up on the wall with ease. Then can be easily pulled off with no mess left behind, and doesn’t damage the wall. Supplied in individual strips, in a 75g pack. Also we have a white tack available, TEB0200.
