Sandpaper Roll Burs 10 Piece Kit (Assorted Grits 240-5000)

The same sandpaper rolls that I use on the Roys Rocks YouTube channel (https://www.youtube.com/c/RoysRocks).
 
This set covers a wide range of grits including 240, 400, 600, 800, 1000, 1500, 2000, 2500, 3000 and 5000 (FEPA P grit). Perfectly suited for opal carvings (and other gemstones/materials like wood/metal). The shank size is 3/32" or 2.38mm.
They are fast wearing but quite cheap in comparison to nova points (which they can compete with: Diamond Pacific Nova Resin Point 4 Piece Set (Small Bullet) | Roys Rocks)
 
Instructions can be found on the tool instructions page (HERE), and of course, there is plenty of extra info on the youtube channel.
