Acrylic stamping block
From Craft-Wiki

The main purpose of a clear acrylic stamping block is to use unmounted (clear) stamps.
These stamping blocks come in different shapes and sizes:
- Square, rectangular, circular, ...
- With or without grid lines to help with straight stamping
- Straight, curved, wavy, ... sides that can help with grip
- Different thicknesses (where a thicker block is usually a bit easier to handle)
Be cautious when cleaning an acrylic block with alcohol, since it might become cloudy.
