8 g (0.3 oz) whisky flask

使い終わったパウチ容器を

ジョーゴとして使う。

先ず始めに、よく洗う。次に底部分を切り取る。

中側の芯を切り取る。

小さい注入口のボトルなどに差し込んで自立できる。

キャップに小さい穴を開けて、さらに細い口先にも応用できる。

不要なときは丸めて収納できる。

At first I wash it well. I cut a bottom share next.

I cut an inside core.

I insert it in bottles of a small injection mouth and can become independent.

I open a small hole to a cap and can apply it to thinner lips.

When I am unnecessary, I round it and can receive it.

Met a couple hiking that shared their scotch with me at the summit (thanks, guys!) out of a Platypus – nominal cost ($4.50), only slightly more weight at 0.7 oz, , widely available, no taste from the container, and no cleaning involved. But then I guess it would only qualify as “BYOG”…

Yukiosan, I am interested in re-using these useful containers also. Can you post a larger picture please. I have not figured out how to remove the inner straw without ruining the package.
Arigato.

Park City IceWater Company sells water in a 16 fl. oz. flask of similar design. Weight is 0.5 oz. I used a bent paperclip to remove the small internal valve.
