A "folding cup" found at a 100-yen shop, Daiso. A portable cup that can be folded into a compact size that fits in the palm of your hand.
When folded, it has a colon and a round cylinder. When you pick it up, it reminds you of the nostalgic toy "Hyper Yo-Yo".
Divide it in two, remove the lid, and pull the bellows-shaped plastic inside to make a cup. The case at the bottom of the glass serves as a base for a perfect sense of stability. With a capacity of 200 ml, it can be used not only as a drink but also as a simple plate for snacks.
Above all, I am glad that the carabiner is hooked on metal fittings and belt loops and does not press the contents of the bag when carrying it. Not to mention outdoor leisure, it seems that you can use it for something even if you take it on a trip!
It's quick to hook it when it dries
