This is a really nice set of stamping tools. It even comes with numbers!
The sizes listed below are not exact. For exact size please consider the measurements below which are in mm for each size letter "A". The width is at it's widest point (bottom of A) and the height from the bottom of the A to the top of the A.
1.5mm = 1.5mm wide x 2.00 high
2.0mm = 2.00mm wide x 2.80 high
3.00mm = 3.00mm wide x 3.80 high
Currently these stamps are unavailable in China. The new ones coming in are from India and are more expensive. If we can get the ones in from China, we will then lower the prices. Get them while you can.
