It comes with two types of rollers: knurled and grooved. Unlike edge pens, this tool allows for even application of the edge finish. It won't get messy like when using pen-type edge finishers or cotton swabs. An edge finishing 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 finishing machine, and apply it by rolling the leather against the roller with the finishing agent evenly applied. Gold-plated for rust resistance, with a glossy finish and durability. ●Notes: Clean the edge finishing machine before the edge finishing agent dries.
