If you put it on the floor, you can store slippers that get in the way on the door or wall! Introducing an item called "Shoe Rack" found at the 100-yen shop "Can Do".
Durable weight is about 450g (15.87oz). Holders for inserting slippers one foot at a time are lined up, and one rack can store one pair of slippers.
Attach with adhesive tape on the back. If you are worried about the tape marks, you can put masking tape on the base or attach a magnet sheet.
Floating the cluttered toilet slippers makes floor cleaning quick and smooth. It also seems to be good to store slippers for visitors behind the front door and shoe box door.
Also, at the author's house, the size of the slippers for cleaning the bath was perfect, so I could stick it next to the washing machine and store it neatly. Why don't you install it in a place you care about?
