This 18oz shaker tin has a reinforced bottom (hence the name weighted shaker) and is designed, like the 16oz tin, to fit inside the 28oz shaker tin. You can make more cocktails at once in a 18oz shaker as it sits much higher in the 28oz shaker and so can fit more liquid. Both the 16oz and 18oz tins are also known as Cheater Tins as they can be inverted in the 28oz shaker and used as a strainer. Height 6", weight 160g.
