This is a die. I used it only once, returned it to its original condition, and stored it. The following is a product description from the manufacturer: ■ Model Number: PA289 ■ Product Name: Die Rectangular R2 ■ Size: 40 x 60mm H19mm ■ Description: This is a die for use with clickers, etc. It is manufactured with Swedish steel, so there are welded seams. When not in use, wrap it in oil paper, etc., and be careful of rust. Please understand that some rust is unavoidable due to the nature of the product. Due to hand bending during manufacturing, an error of up to 1mm is within the acceptable range. It will be easier to use if you fill the die with sponge or leather. ■ Manufacturer: Palette ■ [Note] The color of the image may differ depending on the viewing environment.
