Nipple shields, size M, set of 2. Available for immediate purchase. These are unused items. Recommended for those who experience nipple pain due to chafing. These are everyday nipple shields. The instructions are on the back of the box, which will be included and shipped flat. The box is quite old, but it was already in this condition when I received it from Amazon. Due to shipping costs, the storage case will not be included. The items will be wrapped in bubble wrap for shipping.
