Travel size products, best sunscreen out there.

Great as always but picture is misleading a bit, this is the small travel size bottle not the full size. I should have read better, still like the set nonetheless of course. Heres a picture for comparison.

Great little bag full of sunscreen for my grandson. Glad we had it to take it everywhere with us. A little pricey but he needs it so instead of taking bunches of bottles we had this.
