I started a new collection today:
They're melamine plates, manufactured by LeCadeaux.com. The pattern name is Benidorm. Dishwasher safe (but not microwaveable, which is fine).
Mine were a birthday gift from the darling daughter, purchased at a local gift shop. They are also available on-line through Distinctive Decor.com , Touch of Europe.net, The Frenchy Bee and Amazon When you factor in shipping, prices are pretty close.
We eat outside when the weather permits and I wanted some unbreakable plates to go with the polycarbonate glassware. I have the Vivaldi polycarbonate mugs by Strahl, which are incredibly satisfactory. I also plan on acquiring some multi-use 8 oz glasses, like these from Strahl.
