City Rain is a glass with a built-in concrete coaster. You never have to worry about getting rings on your tables, because it automatically soaks up any moisture.
Each 230mL cup is $US35. Sure that's a little steep but each piece is custom and it's a unique style. I really like when designers incorporate concrete into every day household items. The material is industrial, clean and cool. And in this case, it works for a keeping a road dry, so why not a sweaty glass too? [GNR8]
