PRODUCT OVERVIEW

It is 550 mm (21.7 in) long with a 440 mm round tail 3.3 mm thick, a 58 × 30 mm flag and a metal clip in the head. The round tail slides smoothly through handles and netting, and the tear-off structure means no cutter is needed to open it. The catalogue lists tensile above 20 kg. MOQ is 5,000 pieces, packed 200 per bag and 1,000 per carton.
The round tail passes one way through the metal clip; tear at the release point to remove.
