This is a complete set of everything in the photos. No individual sales. All items are plastic. The orange 160 has faded markings, but they are still visible and can be measured. The pink one was purchased last and used in a rotation of 5 bottles, so it's relatively clean. The other 4 bottles also have minor scratches, but they are still usable. For those who need a lot of bottles^^ For those who don't mind used items because new ones are expensive^^ The drying stand for washed baby bottles was also very useful.
