I just got my company stamps and let me tell you, I have been stamping the hell out of anything I can get my hands on!...I even stamped the bag that held my white chocolate cherry cookies from the bakery. I knew I was out of control when my friend looked at it and gave me "that" look :D.
Company stamps are a good ( and inexpensive) way to brand your items and there is certain ink that allows you to stamp on clear cello and vellum bags cleanly, with out smudging. Its also good if you "forget" or "run out" of company labels, no need to break out the printer late at night, just stamp and be done.
I LOVE MY STAMP!, lol
