Just in, FlexPad has made the E-Z Shaping Block exclusively for us. This Shaping Block is a multi functional shaping tool. Use the balsa side with 40grit sandpaper for hard sanding, use the Soft Yellow Pad side with sandpaper or screen for smoothing out bumps, or change out to the Blue Softie Pad with screen for finish sanding. The block is made of balsa wood and comes stock with a Velcro Soft Yellow Replaceable Foam Pad. Stop by and check one out.
