A3 Acid free card inserts are available in:

White 250gsm card

Black 250gsm card

Burgundy 300gsm card

These are inserted into acid free A3 pockets to enable any two fragile documents to be stored safely back to back. This effectively doubles the capacity of all your acid free pockets, allowing 80 certificates to be stored in each A3 binder rather than 40.

The acid free card provides good support inside the acid free sleeves to protect delicate and fragile documents, including photographs. The acid free card inserts also form an acid free mount for the certificates, making an attractive display in your binder.

Suitable for the A3 acid free pockets in either portrait or landscape format.
