A long time ago I saw a labeling system that I really liked. It was a semi-hard plastic tape, with adhesive backing. You would use a special device to emboss (?) letters into it, applying pressure. You would emboss one letter, then another etc. The tape was extremely sticky and could stick to almost anything. Because no paint/dye was used, it could survive very harsh environments.
Any idea where I could find something like this, thanks.
