Our hole diameter for the pin is 1mm (approx.), the upper diameter of the pin back is 10mm (approx.), the lower diameter is 7mm (approx.), and the height is 7mm (approx.).
The pin backs are made of brass with a Gold colour coating making them strong, durable, and long-lasting. Due to being made from brass, it becomes rustproof and water resistant so you can freely use it in wet and damp conditions too.
Ideal for pins, jewellery, identification labels, name tags, display books, badges, flaps and display books, cords, bags, jackets, lanyards, bags, vests, hats, etc.
