What Artists Are Saying
“This is going down as one of my favorite pottery purchases ever! I use speckled clay a lot and love the look of the clay unglazed but it’s so gritty. It took not even 10 seconds to smooth each piece with these sanding pads!”
— Juliana E.
“I love all the Diamond sanding pads that I've bought in the last couple of years, but there are just some nooks and crannies I couldn't get to with the regular-sized pads (like the joints of mug handles, small carved areas, and pitcher/teapot spouts), so I jumped at the chance to purchase the Diamond sanding file set—and these little tools are just what I needed for small, hard to reach spaces that need smoothing.”
— Erika A.
“These. Are. A. Game. Changer! How did I live without these? The 3 different grits work perfectly to get the bottoms of my pieces sooo soft! Absolutely recommend!”
—Kimberly
“I bought these on suggestion from an online forum to smooth the bottoms of my pots. They are well worth the money, easy, and quick! Game changer.”
— Lisa S.
