I'm a bit wary about the quality of Thinkgeek's stuff. Love getting their spam, and looking at the fun stuff they sell but I also read the reviews of their products and they don't always smell very roselike.
I bought some stuff from them that was okay if it had cost half what it did but was nowhere near as great as they touted it. The glasses may work, don't know, but I wonder if they're worth the asking price quality wise.
$A9.50 (around $US8.90?) and free postage (to OZ) on eBay, so I rest my case.
