They might not be related. Everyone has their own circumstances, so let's not pry. First, the larger one, let's go. This pattern (photos 2 and 3). Hard to see!!! Bubbles here and there (photos 4-6). There are other small ones. Only one like the chunky one in photo 6. Probably a scratch (photo 7). Black dots. My nail doesn't catch, but I can feel them with my finger. The fact that something is there leads me to believe it's a scratch. Probably a scratch. Not dangerous. Scratch (photo 8). The vertical dots at the bottom are different. The horizontal streaks. Well, there's almost none, but there might be more. Scratches on the bottom (photos 9-11). Now, the smaller one. Scratches (photos 13-15) A little scratchy. It's okay to rub it as much as you want, there's no risk of injury. Probably a scratch (photos 16 and 17). Actually... The texture of the pattern interferes, so I can't tell what it is even if I touch it. Anyway, it looks different, so I assume it's a scratch. Probably a bubble (photo 18). I can't reach it from the inside, and it seems like I can or can't reach it from the outside. I can't feel it at all. I think it exists inside. Therefore, it wasn't made later. Larger one: φ (diameter) Almost 8cm Height: A little over 10cm Smaller one: φ (diameter) 4.8cm Height: 7.5cm Excluding the handle and the little pointy parts. The height is not straight, so I'm measuring the highest point. If you're interested, please consider it.
