## Questions & Answers

**Q: Are the grit-to-micron listings in your description correct?  There are a few which do not match other listings found online.**
A: Thank you for your question. The grit/micron units are standard conversions and correct in the description.

**Q: Do they work on acrylic surface?**
A: Hi there,

Thank you for your question. We haven't tested yet on Acrylics. However, this product has a high quality 3 mil high-strength PSA (Pressure Sensitive Adhesive) backing which will stick to a surface.

**Q: Anyone who bought these, what is the difference between this item and sand paper?**
A: Last lot longer and give finer finish I've found. For lower grits use sandpaper and these to true and get your final edges.

**Q: Can these be used to sand/polish resin if both the 3d printing and art varieties?**
A: Thank you for your question. Yes, these microfinishing film sheets work exceptionally well for sanding and fine polishing resin in both 3D printing and art media.
