Softback Sanding Sponge Stick
Infini Model

Softback Sanding Sponge Stick - #220

Tool
$4.50
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.

Question
Whats the difference with these sanding sticks and the premium ultra-precision ones.
Answer
These are softer and larger than the precision sanding sticks. These are better suited to large and curved surfaces. The precision sticks, while not small enough for tiny crevices and pieces, is better suited to handle medium-sized areas and relatively flat surfaces.

The top tier standard!

These are outstanding sanding sponges! Highly recommend over Godhands and Dspiae. The sandpaper is simply better. Smoother, longer lasting, and very economical. These are my new standard!

Awesome and easy to use for beginners

I'm pretty new to the hobby and had previously been using some crappy little sanding stick and nail buffer that came with an Amazon kit. I had thought I upgraded fully by buying a Raser, but I guess I made the newbie mistake of not considering dealing with curved pieces. Enter Infini's sanding sponges. These are awesome. I was a little scared with dealing with so many different grits, but a quick tutorial vid helped with that and I used them on a kit today that came out so so nice. I definitely recommend them.

Amazing how much better...

Amazing how much better the sanding is on curves when the sander conforms to the sanders. Just big enough for gunplay little weird for smaller minis
