I made a beer container & cozy using Astrofoil. This one comes with a strap. *The color of the carabiner on the strap may vary. ◑ This "Full Capacity Warm/Cold Keeper" is designed to keep beer, juice, frozen food, etc. warm or cold during transport. ul Hikers can also use it as a cozy. Summer mountain climbing can be exhausting due to the heat, right? When the distance between mountain huts is incredibly long, it's a hopeless situation to drink ice-cold cola along the way. But! With this, you can always have Coca-Cola ♪♪ Also, when doing a long traverse, you want to reduce the amount of food you carry, so you usually end up with α-rice as the main meal. In such cases, it also works great as insulation (cozy)! ◑ The size is 23.5 cm long x 22 cm wide when laid flat. Weight is 48-50g + strap approx. 14g (There may be slight individual differences) ☞ For 350ml cans, it fits 2 + α (frozen dumplings, etc.) For 500ml cans, it fits exactly 2. ◑ The key feature is that it has a strap, allowing you to hold it in your hand or hang it from your shoulder, offering two ways to use it. Also, to limit the amount of items you carry when camping, I made it the size that only fits two cans of beer (juice), which also helps prevent overdrinking at the campsite. Customize it with stickers to create your own unique 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. *We make each item with care, but there may be slight individual differences. If you are looking for perfection like a mass-produced product, please refrain from purchasing.
