Review on Sanding Sponges Superfine Ultrafine Microfine by John Murphy

Thank you for offering them as a mixed bag with all 'grits' so I didn't have to buy 4 huge expensive boxes! conventional sandpaper and they are much easier to work with and also easier to hold. Note that they are on the lower end of the specified grit and will remove a lot of material when you press on them as they are much easier to press firmly as they are soft.
