    2. MINI HANDLE x 1


    • SAND-LOOP is an ultra-precision sandpaper, compatible with RASER THE BLACK and MINI HANDLE. Adhesive on the back makes it  easy to attach and detach to the dedicated handle.

    • MINI HANDLE has appropriate handling weight and balance to allow precise sanding.

    • Premium finish tempered glass is durable and provides an excellent grip.

    • Each side of MINI HANDLE is composed with a Magic-hook system to secure the SAND-LOOP in place and allows easier attachment and detachment when replacing it. Unlike any other conventional products, it detaches easily and does not leave any adhesives.

    • MINI HANDLE's dual-side design allows easy switching between two sides by attaching two different grits of SAND-LOOP on the Magic-hook on each side.

    • One side edge is marked with indicator labels* to easily distinguish different grits for user's convenience. (*applicable for products since Sept. 2020)

    Recommended Use

    1. Dual-side design allows quick and easy sanding with different grits. Select the two most used grits on each side. 

    2. MINI-HANDLE's weight gives enough pressure for sanding, there is no need to apply excessive pressure. Just relax and rub against the surface sideways. Use the handle’s weight to achieve balanced sanding.
