Unlock simplicity, super strength and ultimate ease. The remarkable 3M Dual Lock Reclosable Fastener can be opened and closed up to 1,000 times before losing 50% of its original strength, for repeated access or repositioning. The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated, the fasteners are hidden from view and leave you with an unbroken surface for a smooth, clean appearance.
