Packing toiletries can sometimes be a challenge so I’m constantly trying to find better suggestions for you. As I’m typing this I’m on a flight and I ordered some wine (surprise, surprise) and as I’m looking at the bottle an idea pops into my head.
It’s too big to be packed in my carry-on bag but then I thought about you. You may be the person that isn’t quite ready to not check a bag but you still don’t want to have the full-sized products with you when you travel. So I think this bottle (or something like it) would be perfect for you.
