This is one of two nipple shields I purchased on Mercari when I urgently needed them for childbirth. I received it in a box, stated as new and unused. Please understand that due to the silicone material, very small dust particles and fibers can easily adhere during storage (see images 3 and 4). I tried using the other one, but the size didn't fit, so I am selling this one unused. Please purchase only if you understand that it has been opened, handled by someone else, and stored by a private individual. The outer box will be folded and shipped as shown in the images.
