Having a toothbrush in your suitcase is a serious risk. The way things get knocked around it could end up smashed or worse. Some corrosive goo could spill in your bag and get absorbed into your toothbrush. Now if you had this case for your toothbrush, that would be one seriously protected toothbrush. This aluminum brush case may not seal the toothbrush from any chemicals spilled, but it’ll at least intimidate them enough to keep them away. Sadly, it’s just a concept design, so no luck on purchasing this.
