Customizable Toothbrush Holder

I have three children and the youngest has trouble remembering which toothbrush is hers and which belong to her siblings.

So sometimes she accidentally uses someone else's toothbrush.  Naturally, this does not please the owner of the toothbrush.

I have found it really hard to permanently mark toothbrushes, so I created a holder for a single toothbrush that can be easily engraved with a name.  Making each child's toothbrush holder a different color has also helped.
