I used this about once every two weeks to check my breast milk supply, as I was supplementing with formula. I sterilized it each time. I stopped using it after about 3 months, so I used it approximately 6 times. It is in beautiful condition with no scratches or stains. I will ship it as compactly as possible, so I may fold the box. Please comment beforehand if you have any concerns.
