I think they're just "wide rim pasta bowls"

Found this, a 12pk of bowls, same capacity but slightly smaller dimensions for $97 dollars (~$30 each vs ~$8 each)

Also Found this, same brand, singles for $16.61

Those are also $44 per plate, so $264 for 6. There's these: https://www.amazon.com/CAC-China-HMY-122-10-Inch-Porcelain/dp/B008M2VM00/ref=dp_fod_3?pd_rd_i=B008M2VM00&th=1

at $100 or so for 12. Maybe split them with someone?

Or for $80, 4 of these: https://www.amazon.com/Villeroy-Boch-Manufacture-Structured-Porcelain/dp/B07CB61T93/ref=rvi_4/144-5694760-4088640?pd_rd_w=wSuxN&pf_rd_p=f5690a4d-f2bb-45d9-9d1b-736fee412437&pf_rd_r=WBA4PWSYDN783ZHPD1HF&pd_rd_r=7d16e6a5-e6aa-4256-9727-131db0e8e61d&pd_rd_wg=xIUqJ&pd_rd_i=B07CB61T93&psc=1
