Metal Plate Stamps, maybe?

[temptress.livejournal.com]

Hey - I received some (metal stamps?) for Christmas...the kind you spread the ink onto just right (did not receive ink) and then press the paper onto them and...well...I cannot for the life of me figure out what that'd be called and how to google the proper use of them.

They're metal, pretty flat, mostly border designs.

Any help? Thank you!!
