Review on Sandflex Sanding Block 3 Pack by Kevin Abner

I bought this product because I thought it would replace sandpaper. It seemed to work like sandpaper. Instead, it behaved like a giant black eraser. Do you know what's written on pencils? How do they dissipate when they experience friction? Yes, it was. Was there sand? no Just a bit. On the plus side they look exactly like the pictures. The packaging was identical to what you see in the photo here - oh and they were delivered very quickly.
