Carta Pura Binding Ring Ø 20 mm
The binding ring is a very handy helper. It helps keeping all punched paper together. It does not matter whether A4 paper with two binding rings or sample or index cards with just one binding ring.
Especially useful for vocabulary learning: All known vocabulary on a booklet and all yet to be learned on another.
Our binding ring is nickel-plated and due to the practical hinge very smooth.
