Deluxe Hardwood Folding Travel 7.5 inch Chess Set - Magnetic

Lovely staunton pieces on a small scale. Great for my disabled husband - not too small to handle, but small enough to pack away for travel. I like the nesting for the pieces inside the box, which folds out into a mini chess board. Magnetic pieces mean he doesn't have to fiddle with peg-board, and less likely to drop them and lose them - but the metal inside the board is well hidden, it remains a beautifully crafted wooden set and board. I'm intrigued by the two spare queens - are queens more likely to be lost or broken than other pieces?
