as advertised, big enough to hold a quart jar sized bundle plus a few standing type Mylar bags (couple 3" x 5" and a 5" x 7.5") plus 500cc O2 absorber easily. Not super heavy thickness, but good for my longer term storage purposes. Bags heat seal nicely with smooth, higher temp range, hair straightening iron. A great buy for me & shipped nicely.
