Utamaro Soap Case with Brush, White

This is a popular Utamaro soap case (with brush) ?
I purchased it on Rakuten and set the soap in it, but ended up not using it and kept it in storage at home.
It's very convenient for cleaning dirt off indoor shoes and socks, as you can scrub the soap while using it.

The color is a clean white.
The brush has firm bristles that make it easy to remove dirt, and there's a spring at the bottom, making the soap easy to use.

It's great for cleaning dirt off children's school supplies and work clothes.
The lid has a spring, so you can even use smaller pieces of soap.

Product size: 13.5cm × 8.5cm × 7.5cm
Compatible soap size: 105×65×35mm

The key feature is the brush that creates a rich lather just by rolling it around!
When placed on the tray, it won't stain the surroundings even if placed while wet.
