What paint should I use for painting a mouse?

[cryptokey]

Hello GH!  I recently purchased an ergonomic mouse, however the only gripe I have with it is its appearance.  Yeah... It's ugly.  So I was hoping that I could make it look a little bit better by painting the non-grippy part of the mouse (of course).  Except, I am unsure of which paint would be best for this.  I need something that will last after daily use, yet is not too toxic that it might be unhealthy in the long run.  Any ideas for what I should use?

Likely Krylon Fusion for Plastic would work.

You could try out cerakote, they have a very wide range of colours, expensive but for such a small area you could use a sampler.

Alternatively you could rough up the surface with a high grit sand paper and use a self etching primer
