If you put it in the mayonnaise, ketchup, or refrigerator door pocket that is running low, it will fall down and become unstable every time you open or close it. I used to put it in a suitable empty container, but I found a special 100-yen goods, so I tried it.
This is the "Flower Mayonnaise Stand" purchased at the 100-yen shop "Ceria". The stand, which is 140 mm wide and 70 mm deep, has two pockets that allow you to stand the seasoning in a tube bottle with the cap down.
It fits in the door pocket of the author's house in just the right size, so I immediately set the mayonnaise and ketchup. Regardless of the remaining amount, it remained fixed even when the refrigerator was opened and closed.
It's made for the refrigerator, so there's no waste in size, and it's nice to be able to wash it completely. If you don't have two things to put in, the space will be wasted, but if you have similar problems, why not take it in? The price is, of course, 108 yen (tax included).
