Just stumbled onto a stainless steel box for sale for $10 online! http://www.zoombabygear.com/item_575/Stainless-Steel-Container.htm My cubic inches to ml says it's around 850, but that's including the domed lid, and approximate. Good for sandwiches and bulky fruit and salads, probably. But cheap! They also have a 12oz stainless steel bottle with nipple cap for babies, but it says a sport cap is available, I guess on request. Also $10. http://www.zoombabygear.com/item_576/Stainless-Steel-Sippy-Cup.htm

Not quite sure this is the right section for this (and it's my own forum! dang!) but anyway - I just saw an eBay listing that may interest people who are looking to stock up on bento boxes. It's a lot of 12 (12!) bento boxes, including many favorites like Lube Sheep, Totoro, etc. I guess they must be used...but hey...12 boxes!
