I saw this product being introduced on Nitori Live, so I bought one to try out. Because the refrigerator door is where you open and close it, it was a bit of a stress to have to take one out and then have the others fall over. The width and thickness of the okonomiyaki sauce and ketchup were different, so it was a bit of a problem, but since I started using this, I can adjust it so even if I buy something of a different size, I can change it. The mayonnaise and ketchup that I use most often are stored at the front, and the yakisoba sauce and okonomiyaki sauce that I use occasionally are stored at the back. Even if I take one out, the others won't fall over! I've solved my problem with this simple attachment. I think I can use it in other places too, so I've decided to buy another one. The price is also low, so I'd like you to try one.
