Blocks, Pens, Marker

We offer a selected range of archive-safe, acid-free writing pads and exercise books, supplemented by reversible and irreversible writing instruments for marking and organising your stocks. In principle, you should avoid using felt, ink or ink pens for the direct marking of valuable originals and unique items. If absolutely necessary, a light, reversible marking by means of an eraser may be applied using a graphite pen.
