Scotch-Brite's amazing bottle cleaner, perfect for washing bottles! I bought it for baby bottles, but it wasn't suitable for plastic baby bottles. I think it's ideal for cleaning water bottles, etc. I will ship it in an envelope. If you have any concerns, please comment before purchasing. The "e" part has been used a few times. Please refrain from purchasing if you are concerned about this. Please check my profile and ask any questions you may have.
