Bosch Professional 3-piece Sanding Sponge S473 Best for Contour Set (wood, plastic and metal, 98 x 120 x 13 mm, accessories for hand sanding)

They don't clog, they last a long time, and are relatively inexpensive- for what you get! The foam backing is flexible so you can bend them to sand curved surfaces too. I restored 6 teak chairs using these, and they are still going strong. This is the "square block" type, the other type has a pack of 3 with one curved end and an another angled end on each block. Also worth getting, despite the higher cost. You might find these cheaper at other places online too, but then you have to pay shipping costs.

I was sceptical but Bosch is a well known brand a little expensive but for 3 thought give them a go....absolutely brilliant sanded and sanded and sanded .....worn me out still really good, bang the dust off brilliantI have some cheap pads which I purchased now in the bin don't last also keep there shape recommended

Got these for several tough sanding jobs and they’re still in totally serviceable shape after sanding several square metres of splintered wood and cracked paint. Buy the best.

Been using to rub down furniture. They’re great in getting into all nooks and crannies. And can be washed when finished using it.

Does what it should. No complaints.

For not a great deal more than many insta-disintegrate foam blocks, they last 10 times longer.

Pad started ripping after an hour sanding soft pine wood. Disappointed with the durability.Seller was also a let down and kept stretching it out until I’ve finally given up. Instead of just posting out a replacement straight away I was offered a 20% refund after 4/5 messages and picture evidence.

Just what I wanted. Nice to use especially to lightly sand between gloss coats.
