I made a beer container & cozy with Astrofoil. This one comes with a strap. *The color of the carabiner on the strap may change. ◑ This "Full Warm/Cold Buddy" was made to carry beer, juice, frozen foods, etc., keeping them warm or cold. It can also be used as a cozy by hikers. Summer mountain climbing really makes you tired from the heat, doesn't it? When the distance between mountain huts is terrifyingly long, drinking ice-cold cola midway is desperate. But! With this, you can always have Coca-Cola♪♪ Also, when doing long-distance treks, you want to reduce the amount of food you carry, so you usually end up with alpha rice as your main meal, right? In that case, it's also very useful for keeping things warm (as a cozy)!! ◑ The size is 23.5 cm (height) x 22 cm (width) when laid flat. The weight is 48-50g + strap approx. 14g (There may be slight individual differences) ☞ For 350ml cans, it fits 2 cans + a little extra (like frozen gyoza). ☞ For 500ml cans, it fits 2 cans perfectly. ◑ The special feature is that I made it so you can attach a strap, allowing for two ways of use: holding it in your hand or hanging it from your shoulder. Also, to limit the amount of items you carry, which tends to increase during tent camping, I deliberately made the size to hold only two cans of beer (or juice), which also helps prevent overdrinking at the campsite. Decorate it with stickers to make it your one-of-a-kind original! * Due to the nature of the material (Astrofoil), the aluminum part may peel off if rubbed. * Items other than the beer container cozy (stickers, etc.) are not included. * Each item is made with care, but there may be slight individual differences. Please refrain from purchasing if you are looking for perfection like mass-produced items.
