I have tried many different bottle brushes & these are by far the best! The 2 deluxe brushes are very sturdy and clean even the dirtiest stuck on formula bottles. The sponge brush is great for cleaning nipple rings but not the bottle as the foam falls apart after several uses. The small brushes attatched to the deluxe brushes are ideal for cleaning the nipples. Overall, this is a great product!Get more detail about Munchkin Bottle Brush Compbo Set- 2 Deluxe and 1 Sponge Brush.
