disposable heat pack

Aren’t you cold???

Have you ever tried this disposable heat pack?
Very useful and popular stuff in Winter.
You can buy everywhere—Japanese convenience stores, drug stores e.t.c.

 

It is a packed iron-powder product.
Inside of a disposable heat pack, there are iron powders, water which accelerates iron powders to get rusted, salts, vermiculite as water retention agent and activated coals which acquires oxygen in the air.
Great invention.
it lasts 10-24 hours(depend on product)

After used it,
put this in your shoes, boots, whatever—
It deodorize, because of activated coals.
Please try!

There are so many kinds of disposable heat packs  and makers in Japan.
