Zip-bag zipper

A zipper for any zip bag.
If you have zip bags with lost zippers or zip bags that do not come with zipper...here you go.
Just flip it with the edge with 2 slots on the bottom. It has built in support for the other side.
For bags that don't come with zippers you will have to cut the top flaps with some scissors.

NOTE: I use the term "zip" and "zip bag" as a generalized term. I do not refer to any propriety copyright holder. If anyone has a better name for it, please contact me.
