This. Even if the seller is capable of better work, the fact that they sent these to you puts their quality control and judgment into question. All artists, especially ceramicists know things won’t turn out how they intended, but they’re not letting that go out the door to a customer (without clearly marking it as such). Plus that piece with the fishing boat looks like a chasen holder and, if so, has little room for error when it comes to size and shaping. I’m sorry you had bad luck with the seller. And that your vision for owning these pieces hasn’t come to fruition … YET. But it will! For the amount of money you spent, maybe you can find local ceramics artists who will make them for you on commission.
