They are Playtex disposables. My daughter prefers them and so do I. Though we don;'t care too much for the silicone (clear) nipples. Toys R Us does carry them. Target can be difficult. The one by me only carries a few and they are usually out of the latex nipples. Walmart is a search because they don't carry many at all. You may want to try online and see if you can get a better deal on a set of them.
