Two food-safe silicone toothbrush covers, in blue and white. Fit most standard toothbrush heads. Dishwasher safe and can be sanitised in boiling water.

A toothbrush loose in a wash bag touches everything in that bag. Two and a half dollars fixes that permanently, and a silicone cap beats the plastic clamshell kind because it grips rather than falls off.

Food-safe silicone also means you can actually clean it — boiling water or the dishwasher, rather than the hopeful rinse a hard plastic cover gets.

Two in a pack, so there is one for each person or one as a spare for the one you will leave at a campsite.
