I purchased these rolls from a website around May 2025 and used 4 rolls, but I no longer need them, so I'm selling them. There are a total of 36 rolls. 7 packs of 5 rolls each 1 single roll (opened, roll unused) One pack has been opened for use, but the others are unopened. Please refrain from purchasing if you are concerned. Thank you. ■Quality: Medium-term preservation ■Paper width (mm): 58 ■Roll diameter (mm): 80 ■Length (m/roll): Approximately 80 ■Paper thickness (μm): 65 ■Thermal roll paper Suitable for use in cash register receipts, tickets, etc. ■Long rolls for great value The paper is thin, approximately 65μm, so each roll is relatively long. ※Please confirm the compatible roll paper size for your device before purchasing.
