Review on 📬 Premium A4 Orange Rubber Stamp Sheet for Laser Engraving Machine (2.3mm Thickness) by Sasha Hsiao

I bought my first sheet a few weeks ago and was pleased with the results when stamping on my K40. The laser treated gum turned to a white powder and peeled off easily. Satisfied with the quality of the first sheet, I ordered two more sheets. These were slightly lighter in color. When I lasered them there was a lot more smoke than the first panel I tried. When I removed the stamp from the machine there was black sticky burnt rubber everywhere the laser touched. (I used the same settings for this sheet as the previous sheet.) It's very difficult to wash off that sticky burnt gum. It was clearly a different gum than what they sent me earlier. Buying from this seller is a gamble.
