Kajaia Acrylic Leather Stamping Tools Leather Stamp Guide Leathercraft Supplies, 5.91 x 2.05 x 0.08 Inches

The pieces have to be assembled, they do not fit snug so will not hold in place, but placing a flat washer between two opposite corners will fix that, thought the numbers were printed backwards but there is a protective coating which needs to be removed and then it's clear instead of white.

This is cheap junk. The measurements were printed backward. You have to put it together and that’s not as easy as it looks. It’s flimsy and not tight. Mine was even stained red in one spot. I will return.

WORTHLESS TOOL: This is flimsy and not even assembled when it arrives. It can be adjusted to size but not secured. Measurements are not in inches and its length is too short to be useful for all projects. I did way better just eye-balling my lettering. Don’t waste your time on this item.

But does work well with small letter and stamps

The numbers are backwards. Received three female screws and five male screws so I cannot assemble it

First off, this can be used on stamps up to 3/4", so if you need larger, look elsewhere. Second, the way it is constructed with the screws the manufacturer used, it can not be tightened at all, so it is always loose. Third, the measurements used are Metric and not Imperial, so you get centimeters and no inches. Finally, as others have noted above, the plastic is semi-opaque and the ink is printed backwards so it is very difficult to read unless it is at just the right angle and just the right light. It isn't worth it just to save a few bucks.

When using it, is difficult to keep it in the position you set it up in. Very flimsy

Very loose. Cheaply made had to put together isn't hard to do but the screw and nut dues fit correctly easly moves
