I considered buying their 12" drawer set12" drawer set ($79.00) in lieu of both the above, but decided against it, since it would end up costing more, and at this point I would rather have two sets.

Edit, two days later: I talked to the sales rep again, and he let me know that they actually do not have any drawer sets of that size, and that a item number mixup led to advertising of a 7.5" x 7.5" drawer set instead of a 7.5" x 7.5" hinged top set. He offered to pay return shipping as well as the refund, but also gave me the option of keeping the set and letting him send me a 5" x 5" drawer set5" x 5" drawer set free of charge or a $20 discount on a larger set. Naturally I appreciated this offer very much, and accepted the 5" x 5" set. So now I will end up with three sets. I unpacked the 7.5" set which I had set aside, and tested it.
Now naturally I couldn't live with the three nearly nonmagnetic pieces, so I peeled off the felt of one of the faulty pawns, pried out the magnet, and had a look. It was a cheap, grainy sort of magnet, but strong enough for its size that I almost gave up trying to come up with a better substitute. Suddenly I bethought myself of some old MagnetixMagnetix kits we had stored away. Armed with pruning shears, I removed a magnet off the end of one of the toys. It was about the same diameter as the chess piece's magnet - a smidgen smaller, but twice as thick, and at least twice as strong. I drilled the pawn with a power drill to make room for the new magnet, fitted it tightly in, so it didn't need glue, and glued the felt back on with white glue. Voila! A pawn resurrected! I did the same with the other two pieces, but after I placed them on the board, I discovered that I would like all the pieces to be that strong. For the next two hours, I removed Magnetix magnets, peeled off felt pads, pried out magnets, drilled holes, forced in magnets, glued on pads, and set the pieces on their sides to dry overnight. The next morning, I was suddenly very fond of my chess set. The only drawback to the stronger magnets is that the pieces tend more now to stick to one another if you are not careful with a piece in transit near other pieces. It isn't on the level of a big problem, though, and I like the new magnets much better than the weaker ones. Now I can shake the set while it's sideways, and only the Black king will move (I must have set the magnet too far in).
