Hendrik Ball, aka Grand Illusions, is well known on YouTube for featuring the elderly gentleman with the largest toy chest of the most interesting and obscure toys, gags, and gizmos from the past. 

This brand new video, featuring a Japanese zip bag from YKK made in the 80’s, is particularly interesting. What looks like just a fabric strip can be zipped up into a very real purse or small pouch.

The host demonstrates how to zip up and create the four different zipper bags in the series, and he even shows how they are all engineered to interconnect to create larger, more complex bags.
