Use VELCRO® Brand Stick On Squares instead of nails, tacks and glues. This pack contains 24 sets of white hook and loop squares, which can hold up to 300g per 20mm x 20mm piece. Perfect for DIY projects around the home, school or workplace, just make sure the surfaces are clean and dry before sticking the adhesive side down. And allow at least 10 minutes for the adhesive to set before use.
