NES Console Cleaner Insert 1UP Card Replacement

I repair and restore Nintendo consoles of all kinds and love the 1UP Card console cleaners, but I don't love how quickly the cleaning insert gets dirty and needs replaced. You can buy a replacement from them for $10 or you can print out one of these. The mystery pink coating is actually lens lapping paper 3 micron 8000 grit. You can buy 5 sheets for $15. Enough for 50 refills! Amazon link to paper:https://a.co/d/cMcggxLCut the sheet to 93mm x 60mm, it's self adhesive, so just stick it on.This insert should also work in a regular NES cart if you don't have the 1UP Card.
