MY BAD for not realizing that an aerosol product of one ounce equals a trial size or one of the samples that comes in a box. For what I paid, I guess i expected a full size product. And this is not a full size product. It works well, and I really like it. But I'm not delighted with the price/quantity ratio. Birchbox guidelines for reviews ask us not to mention price, so I won't do that. If you are considering buying this product, be clear that the full purchase price on the site provides you with a product that can fit in your purse. A small purse.
