Used for applying edge finishing agents such as Tokonole and Cobasuper during edge processing. Apply an appropriate amount of the finishing agent to the head and apply it to the edge. The roller type allows for very stable application. In addition, the groove carved into the head stores the finishing material, making it difficult to stain the grain and flesh sides, and allowing for even application of a consistent amount. This is a roller type that does not use bearings in the rotating parts. It is screw-fastened, making maintenance easy and eliminating failure points, so you can use it for a long time. It is heavy and has a high-quality feel, allowing for comfortable work. Material: Stainless steel I also sell other leathercraft supplies.
