Honestly obsessed with the texture of this! It's like actual whipped cream but for your face and doesn't leave me all red like some of those harsher scrubs do. My skin feels so soft after using it.

Picked these up for a tabletop glue-up and I'm pretty impressed. The steel bar is stiff enough that it doesnt bow too much under pressure, and the quick release actually works without sticking like some of the cheaper ones I've tried. They aren't industrial grade, but for a hobbyist shop, they're perfect. Plus getting 4 in a pack is a total steal.
