It's time to pay attention to the hygiene of bento boxes as the temperature rises. You can't let go of the ice pack and the cold bag when you carry it around.
The one I have been using since last year is the 100-yen "Craft Lunch Bag". It looks like a paper bag in a store, but the aluminum vapor deposition sheet and foamed polyethylene are stuck inside, which is useful for keeping the contents warm and cold.
New products will be introduced one after another at each store this year. The 100-yen shop "Can Do" sells tote bag types that are convenient to carry around. The size is width 27 (bottom 16) x height 15 x gusset 12 cm. With a zipper on the top.
At the 100-yen shop "Ceria", I found a black color that seems to be easy for men to use. The size is width 20 x height 20 x gusset 10 cm. Opening and closing is a velcro type.
All of them are just the right size to put a two-tiered lunch box, soup jar, 500ml (16.91us fl oz) PET bottle, etc. Even if you put an ice pack, the bag will not get wet due to condensation, and the outside will not tear even if it gets a little water (wipe it off immediately). Of course, the price is 100 yen (excluding tax). Get it for the summer ♪
