Review (5/5): Great Size! I love the bulk package as well.
I do a lot of traveling, and also take my toiletries to the gym each day. These bottles are the perfect size. The bottles are small enough to pack in a carry-on. I can fit a number of them, along with my other items, in the TSA required "quart sized bag." The fact that they come in a 12 pack also means I can pack some in my carry-on and put additional bottles in my checked luggage if I expect to need more than two ounces on a trip. I am really glad that I ordered these, and would recommend them to "gym rats" and travelers everywhere.
