Review: Received wrong item - I receivd a pair of work pants. They were probably worth more than than the cost of these flasks, but a 40" waist and 24" long just wont fit me. I returned them and received the correct product, but was credited for a lower priced item that I had ordered at the same time. This item is great, and I'm sure all the headaches I've had with this order are the fault of desertcart, and not not the seller.
