Kill germs the natural way with The First Years Modular Steam Sterilizer & Dryer. Natural steam kills 99% of common germs in minutes; there's no need for harsh chemicals or additives. The modular design, with two trays provides plenty of room for sterilizing while saving counter space. The top tray is perfect for bottle nipples, baby teethers, breast pump parts, pacifiers and other small newborn essentials. The bottom tray is specially designed for baby bottles, cups and larger items. Use either tray, or both depending on your needs for the day. The clever design of the bottom tray directs steam deep inside bottles and both trays fully circulate the steam to make sure every surface is covered. The dryer option leaves items dry and ready to use, and this steam sterilizer doubles as a handy storage space, keeping the things inside sterilized for up to 24 hours. Bottle not included.
