Are the grit-to-micron listings in your description correct? There are a few which do not match other listings found online.

Thank you for your question. The grit/micron units are standard conversions and correct in the description.

Do they work on acrylic surface?

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.

Anyone who bought these, what is the difference between this item and sand paper?

Last lot longer and give finer finish I've found. For lower grits use sandpaper and these to true and get your final edges.

Can these be used to sand/polish resin if both the 3d printing and art varieties?

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.
