It comes with two types of rollers: knurled and grooved. Edges cannot be coated evenly with an edge pen. Unlike using a pen-type edge coating tool or cotton swabs, it won't get messy. An edge coating machine is necessary to shorten the working time. Simply put the edge ink in the reservoir and slide it. It's done in 1-2 minutes. How to use: Put the edge finishing agent into the edge coating machine, and apply the leather to the roller with the finishing agent evenly applied, and roll it. Gold-plated for rust resistance, with a glossy finish and durable. ●Notes: Clean the edge coating machine before the edge finishing agent dries. Color...Gold Uses...Leathercraft
