This tool is smaller than I expected (only 5.5 cm high, a bit more than 2 inches)
but it's so good and the size is perfect !
Well, it's very easy to use, in seconds you get the foam without wasting product, plus you have two sides: one for massage and one for exfoliation,

both sides are gentle. I like to use it on my nose, no irritation.
It's a silicone brush, no problem cleaning it and the sponge inside can be removed easily.
This would be a great stocking fillers and a nice gift for oneself (the occasion doesn't matter).

How to use (in english) :

Wet the silicon brush, squeeze cleansing foam into the sponge hole at the bottom and work up a lather by rubbing it with your hands.
Use the fine silicon bristles to cleanse over the face.
