Alessi (DL's supplier) sells things similar to what they sell on board although they are pricey.

Another option is Duralex dishes: https://www.duralexusa.com/collectio...owls-with-lids

They are very durable and they have lots of different styles (available on Amazon and direct from the store). We use the smaller rectangles/squares to prepare small servings of food for our son so we can offer a few different things in small portions.
