These are some fantastic plates. I got six of them through the Kickstarter campaign -- gave two to my brother and kept four for myself. They've withstood several moves (on my part) and a household of small children (on his part) and only one of the six plates has gotten damaged.
I love them not only because they're super sturdy and functional but because they really do a great job of masquerading as normal Delft-esque tableware. I've thrown many, many dinner parties where guests will sit down and only after finishing their meal will they go, "waaaaait a second..."
