Natural, non-dyed cotton ties measure 18, 24, or 36 in. from knotted end to knotted end, and are held together by a small metal ring. The ring allows the tension to be adjusted to allow easy insertion of objects, and then the Grip-Tite can be tightened to ensure a snug hold. Use them to hold books with fragile bindings together, to group collections of unbound periodicals, or to keep objects such as maps or drawings rolled up. Grip-Tites may be used repeatedly, they will neither stain nor stick to objects they hold, and they donâ€™t crease, tear or crush fragile artifacts. They are sold in packages of ten of a size.
