Sanding sponges play a very specific role in your arsenal:
They adapt to any surface shape, including complex curves and convex surfaces that flat sanding sticks or files cannot reach.
Being less rigid than these, they can conform to the surface and achieve perfect results without creating "flat spots" in pieces like wheels, barrels, fuselage bodies, Gunpla arms, or legs...
They can be cut into small pieces and, held with a pair of tweezers, reach hidden or inaccessible spots.
These sponges by DSPIAE are available in two sets, one with grits ranging from 180 to 800, and another one ranging from 1000 to 2500.
They will cover your needs going from the coarsest one used to eliminate large chunks of plastic, to the finest one used for polishing pieces including clear ones.
They both come with a 5 compartment storage box.
We have to prepare each shipment individually as they are ordered, so allow it in 3-4 weeks to arrive in the USA/Canada (to be safe) and 3-6 weeks rest of the world, though they are usually delivered much faster.
