Ideal for use in the office, the 3-in-1 Accounts Stampstack features 3 commonly used document words including COPY INVOICE, PAID and THIS ACCOUNT IS NOW OVERDUE. These stamps don't need a separate ink pad and with their compact, stackable design they can be stored in any order for quick use. Small, but useful, this Stampstack will fit into a bag or briefcase so you can take them with you on the go, which is great if you're based across many offices.
