Easily close the cardboard lid ♪ I found a goods called "cardboard lock" at the 100-yen shop CAN DO and tried it.
Goods that can close the opening of a cardboard box without using tape. It has a mysterious shape like a combination of a stick and a plate. To use it, just insert the stick between the cardboard flaps (lids) and slide it. As a result, the inner flap and the outer flap are sandwiched together, and the flap is closed tightly. If you use two per cardboard box, you will feel more stable.
Although it is a simple method of fastening, the "cardboard lock" is much easier than tape. If you have a cardboard that doesn't need to be firmly fixed but you want to keep the lid closed, why not use it? The price is 108 yen (tax included) for 2 pieces.
