old Blue Magic cracker tin or cookie jar, glass knob w/ crystals, blue willow print

Mid century vintage Blue Magic blue willow print metal canister with the glass knob still full of the crystals. Canister measures about 7" x 7" overall, with glass knob above that.

There's some rust spotting to the interior of the tin, but this looks pretty good overall, exterior not terribly worn or discolored. The crystals look good, and there's instructions for use on the inside on the lid. I have no idea how well this will work at well over 50 years old, though!
