This table-top pen-style sand blaster is a “Kate Wolf” design for Wolf Tools and is manufactured by “Ikohe”. It can sandblast metals, glass, wood and other surfaces. It has only been used a couple of dozen times and is quite clean. It comes with 3 pieces of clear plastic that attach to the inside of the upper lid to prevent the media from permanently scratching the plexiglass of the unit (1 has been used, the other 2 are brand new). Also included is an extra set of heavy duty latex gloves, and extra ceramic nozzles. I’m including an unopened box of “fine” media along with the used “extra-fine” media that was in the unit. It operates with a pressure regulator at 42-70 PSI. This unit allows for 2-handed operation and the pen nozzle can be attached on the inside of the unit or can be used by hand. The unit measures 20″Lx17″Wx17″H and weighs 12 pounds. Comes with an instruction manual. See the Youtube video for operation.
