costoo stands for well designed, functional and revolutionary cosmetic tools. While other COSmetic TOOls are just a kind of useful, costoo cosmetic tools are state of the art
this hairdryer must be a costoo.

I messed up my make up, i wish i would have some of these costoo tools

Oh i stained my ears while colouring my hair, next time i better use some costoo tools for them.
