Rainbow Toolbox

First, you would need a box carrier

 You also need your canvas (110 pieces)

And attach-on nails

 
Like a true surgeon, you need your dotting tools

And who would have thought, this doubles up nicely as a nail-remover tool and a dotting tool

 Cotton buds to remove nail polishes

And alas, the nail polish remover

 
You know how sticky tape becomes? Use this label sticker instead, sticky free!

And may I present the rainbow!  

And you're done!
