Softback Sanding Sponge Stick #600

In stock

Unlike regular sandpaper which is prone to wrinkling and tearing, the cushioned sponge backing of Infini Model’s Softback Sanding Sticks is designed to follow the contours of your project beautifully, resulting in a finer finish in less time. Using an advanced manufacturing process, Softback Sanding Sticks abrasive grains are adhered to the backing with an electrostatic charge, providing a uniform sanding surface and longer life as compared to typical sandpapers which are uneven, inconsistent and held together with glue. Plus, Softback Sanding Sticks can be used for dry or wet applications for maximum versatility. Each stick is double-sided for twice the life, with a semi-flexible plastic backbone in the middle for a firm grip and added pressure when working in confined areas. Set of eight 6-3/4” x 1-1/8” double-sided Softback Sanding Sticks includes one each 220, 400, 600, 800, 1000,1500, 2500 and 4000 grit. 2-pack refills of each grit available separately. For even more applications and finishing options, see Infini's Softback Sanding Sponges, in grits from 220 to 1500.

Awesome tools at an affordable price!

I picked up the full set. I'm a bit new at the hobby, and always been a little nervous around subtractive tools (cutting tools, sanding etc). These are great! My favorites are the higher grit sticks (800-4000). I've been using them with my Gunprimer Raser when either the Raser is too big/awkward to use, and to get a final finish that I'm happy with. Raser or a high grit sponge to get things roughly smooth, and a few swipes with the 1500, 2500, and 4000 and the parts look great! Glad I picked up this set!

These sanding sticks are absolutely excellent! Great for nub removal and inhaling lots of plastic dust!

Best soft sanding sticks I have ever used

These last forever. They use a special process to make these that makes the grit stay on for a long long time. Just rinse off the dust and go.

Wont use any other brand anymore

These are excellent. Large-sized sticks with long-lasting texture. "Soft" but still firm enough to sand flat pieces well. Really awesome, highly recommend.
