This is a set of MAX ER-UD cards and ink ribbons for time recorders. The time recorder broke down, so I bought a new model and no longer need these. There are 65 cards remaining, and the ink ribbon was replaced only a month ago. The ink ribbon lasted 8 years with light use, so I think it's still perfectly usable. ER-UD Card ER-IR100 ER-110SU series, ER-60SU, ER-180UD etc. Ink Ribbon Type: Time card paper
