Our foolscap acid free card inserts are available in the following colours:
White 280 micron
Burgundy red 350 micron
Pink (birth) 230 micron
These are inserted into acid free foolscap certificate pockets to enable two certificates 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 deluxe certificate binder rather than just 40.
