Vintage K&W Block Seal Head Gasket Repair Metal Can - Full -- This vintage K&W Block Seal Head Gasket Repair can is made of metal.  The can measures approximately 6"H x 2 1/2"W.  There is a dent in the can, running most of the length of the can under the word "Block".  See the images.  I tried to document the blemishes.  There are some scratches in the paint as well, but none that affect the display of the can.  The can is unopened and full.
