Reusable Hinged Jar Zipper Bags - Set of 9
Available at: Uncommongoods.com
These shape-shifting mason jars can go where no glass container has gone before. When brimming with dry goods and snacks, they stand upright just like classic containers, but once you clear them out they fold flat and fit in a tidy stack inside your drawer. A zipper closure keeps the contents secure for easy transport, and the durable polyethylene material can be reused endlessly if you give it a quick scrub between uses. Made in China.
