Query: a great thing, but don't leave it in the car!

I love chess, and have been a student of the game since I was 10, collecting numerous chess books, sets, computers, etc. I should be a grandmaster by now, but how many people have the time for that. My father-in-law gave me this Drueke set as a present. Very nice. I do find the proportions of the pieces to be a bit strange, but the magnets are by far the best ones I've ever seen in a magnetic set. I left this in the car recently during a hot spell, and the plastic case has melted. The board itself didn't melt, so from the outside it looks like a Salvador Dali object. I'll probably replace it, as I feel bad about letting it melt.
