It's truly illusionary! I would like to introduce the "silicon magnet clip" I found at the 100-yen shop CAN DO because it was very convenient.
Clip made of silicone rubber, steel and magnet. Since it can be bent freely and fixed with a magnet, it is useful for fastening various things such as cables, bills, coupons and memos. If you bend it and make a mountain, you can use it as a smartphone stand! You can also use it in a stretched state and stick a large leaflet on the refrigerator door.
The approximate size is 113 x 20 x 6 mm. The price is 108 yen (tax included) per piece. There are plenty of color variations, so why not buy more than one and use them in a variety of situations?
