Box Bits 2 – Concealed Barrel Hinges 5mm

These solid brass hinges are ideal for pen boxes or small jewellery boxes requiring a low profile hinge. They are designed with glue retention lines for securing into the box and lid with epoxy resin glue. They work best on stock between 9m – 12mm, and require both stock pieces to be chamfered at 45º for effective hinge action to occur.
