Freak coincidence - I took one of those for my chai loving MIL as well on my last trip and she too loves it (obviously not for using though as it's far too special for that now)
Thats really funny, bcos my MIL WOULDN'T USE HERS EITHER! She put it in her display cabinet, lol. I said you should use it, she said no, I don't want to ruin it!
