This tool has at least two uses. Primary use is to sand concave surfaces, like front edges of books with rounded spines. Depending on the size of the book and the curvature radius, you choose tools of different sizes.

The other use is as a counterpart of the rounding tool we also sell at this shop (or any other rounding tool you may have in possession). This round tool works as a replacement of the pestle used to press the spine into the rounded form.

- Tools are sold in diameters from 10 mm to 50 mm
- Length: 4 cm
However, you can also make a customized order for larger diameters and longer tools.
Please attach your requests on diameters as comments to your order.

Prices for different diameters:
- 10 mm: €5.95
- 11-20 mm: €6.95
- 21-30 mm: €7.95
- 31-40 mm: €8.95
- 41-50 mm: €9.95

You can also order a set of 5 round sanding tools with a significant discount.

If you plan to use this tool not only for sanding but also for rounding, please consider ordering a diameter that would fit the grooves of you rounding tool. Typically, the diameter should be 2-5 mm smaller compared to the diameter of the groove. However, that also depends on the thickness of cardboard and covering materials you use to create the spines.

These are beautiful. Mine were held up in US customs during Covid shutdown, but this was not the seller’s fault. They are large enough to make a versatile sheet of paper.
