Shinzi Katoh Bento Sauce Bottle - Bento Box and Bento Accesories Store for making lunch http://www.from-japan-with-love.com/shinzi-katoh-bento-sauce-bottle.html
This is part of Shinzi Katoh's &quot;ringo&quot; series. &quot;Ringo&quot; means &quot;apple&quot; in Japanese.
There are 3 little bottles and one little &quot;suction&quot;piece that allows you to transfer the soy sauce from the bottle to one of the little bottles. This is a cute way to take sauce with you for lunch!
Each bottle holds 4ml. The temperature range is -20~80 degrees Celsius. I would wash these by hand.
