I bought 3 oz. plastic bottles and tubes for $1 each, then just filled them from larger bottles of suntan cream and after-sun aloe gel. I used a waterproof marker to write on the tubes/bottles. 3 of them fit nicely into a pint zip-top baggie (heavier freezer baggies are best); then I could put several of those pint baggies into a larger quart baggie (to prevent leaks in my suitcase). ** Much cheaper to do this than buy suntan lotion later, when you arrive at your travel destination! And, this is how you can take your favorite shampoo and conditioner with you on the plane. *
I found these at Walmart (not Neighborhood Mart) ~ where the skin care, shampoo, cosmetics are ~ there should be an area there for travel-sized products and also refillable travel containers.
