Why you need it?
"Small or large?"...That is the question
1. You buy small first, but it can't fit all your toiletries for a long trip.
2. You buy a large one, but it's too bulky and won't compress at the end of that long trip when all you have are empty bottles you throw away.
3. Most toiletry bags are designed awfully with one large "carry-all" pocket where your toothbrush meets other "not so hygienic" stuff inside. Besides, it is literally impossible to find anything in those large dark black pockets. It's a mess.
We know your pain. We've got a solution!
