Hi I have 4 boxes of ready to use Nutramigen formula bottles, each box has 6 bottles and 6 nipples in them. So all together there is 24 bottles. The formula is already per made in each bottles ( you do not add water). These are 2oz bottles. I am selling because my daughter was switched to another formula so we no longer need these. The expiration date on all the boxes is August 2010. give me a call at 937-324-4670.
