This is a specially designed adhesive flat anvil block made to work seamlessly with the Tonosho letter stamps alignment jig. It eliminates the hassle of using tape and provides enhanced stability. Once LEGO blocks are secured onto the adhesive anvil plate, the alignment jig can be quickly swapped, just like assembling LEGO pieces, allowing you to achieve your desired letter spacing effortlessly. It can be used as a standalone adhesive flat anvil block or fixed to a workbench. The two clamping screws on its surface can secure objects in place. Additionally, it comes with a miniature clamp and a puncher, making it ideal for engraving small items.
