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 work time. Simply put the edge ink in the reservoir and slide it. It's done in 1-2 minutes. How to use: Place the edge finishing agent in the edge finishing machine, and apply it by rolling the leather against the roller with the evenly applied finish. Gold-plated for rust resistance, with a glossy finish and durability. ●Notes: Clean the edge finishing machine before the edge finishing agent dries.
