3M 261X Aluminum Oxide Lapping Film, 9 x 13, Multiple Grit Bundle Package, One Each 0.3μm, 1μm, 3μm, and 9μm

The lapping film received mixed reviews from customers. Most users praised the film for its thinness, which helps in keeping surfaces flat. The high-quality fine grit was commended for providing a mirror-like finish when used progressively. However, some users were disappointed to find wrinkles and creases on the film upon arrival, making a significant portion unusable for precise polishing. Despite this, many customers found the film to be effective in polishing various items, including watch parts, straight razors, and knives. The cost was generally perceived as worth the quality of the product. Overall, the lapping film seems to be a reliable option for achieving professional polishing results, but improvements in packaging to prevent creases may be necessary. **
