The uBrush - customization of your brush, the way you want it, for an affordable price. This brush consists of two pieces that can be interchanged to create the look you want.You can add a washer to this order that makes knot installation slightly easier. The handle is meant for a 24mm knot.
You will first glue in the washer, then glue in the brush on top of the washer. I would recommend this option. The washer comes loose and not attached.
