Hook and loop tapes are constructed with precise detailing and strength to ensure maximum adhesion, yet leave no residue. Resistant to breakdown, rot, abrasion, and wear, they maintain performance even after more than 2,000 attachment and detachment cycles. Can be cut to desired length and applied to any clean surface for various mounting needs, including plastic, porcelain, wood, glass, all types of metal and alloy surfaces, painted surfaces, and other dry, smooth surfaces. Self-adhesive tapes: 8 meters of loop tape and 8 meters of hook tape. Dimensions: 8 meters long x 20 mm wide. Industrial-grade Velcro made of durable nylon, with a strong adhesive backing. Adhesive reaches maximum bond strength after 24 hours. Wait 24 hours before pressing the hook and loop strips together to join two objects. Self-adhesive Velcro tapes are moisture-resistant and weather-resistant, suitable for both indoor and outdoor use. Durable hook and loop fibers make them ideal for long-term tool organization, hanging, mounting, displaying ornaments, storage, and many other household applications. Note: Self-adhesive Velcro should not be used on leather, PU, faux leather, fabric, brick walls, tiles, cement, thick fabrics, plush materials, concrete walls, muddy walls, oily polymer surfaces, flexible vinyl, or underwater.
