I don’t know if they are the same ones, but I have a set of Duralex prep dishes and have been happy with them. Duralex are super durable. Just be aware when they do break they shatter everywhere.
If you want something other than glass bowls you can search for custard bowls (think the little cups crème brûlée comes in). Those are usually porcelain and work just as well. Could be good depending on your aesthetic.
