that is sooooooo adorable. i'd buy it right now if i had some money. i think you should sell it for about $40-50. that would be a very reasonable price. good luck!
sorry my opinion might offend you but i kinda have to say that it's not very convenient looking and is kinda cheating... it'd be really awesome if you could make a purse that LOOKS like a tide bottle. maybe you could make it out of felt.
