Talmud Fridge Magnets
Of course, there's no particular reason you should want to arrange the notes on your fridge according to the Orders of the Mishnah, but then again, if you're enjoying this site, it's probably the sort of thing you would do. Isn't it.
You get the six orders (Zeraim, Moed, Nashim, Nezikin, Kodshim, Tohorot) turned into magnets under bubbles of clear glass. The magnets are fairly strong - they'll hold two sheets of paper - and they're a bit under an inch across. Colours will vary, but look, I'm an artist, it's no pleasure to me to send you something that looks awful, so it'll be pretty, just maybe not the pretty that's in the photo there.
$7 plus shipping ($1.50 US, $2.50 international)
The Yeshiva Student's Highly-Educational and Immensely-Useful Fridge Magnets
Yes. If you thought the Talmud ones were geeky, you don't even want to be thinking about this. With this set you get the first page of six yeshiva classics, once again under bubbles of clear glass. The glass magnifies them, so they are actually recognisable if you know the page layouts, which is why they are Highly Educational.
Specifically, what you are getting is: the Vilna Shas, the Rif, the Yerushalmi, the Tur/Beit Yosef, Jastrow's dictionary, and Torat Hayim (because all yeshiva students study chumash).
