The small plates have only been used 2-3 times. The other one has been used a few times, but not often. You can see pinholes like in photos 4 and 5, but they were there from the beginning. That's how they're made. These are not defective products. They were purchased as genuine products ( ˘ᵕ˘ ) Please purchase if you understand. The deep dish cup is 13cm in diameter and 7cm tall, so it seems like it could be used for salads or mini rice bowls!
