based on the pages of my book,
"the alPHabet book for little phans"
each 2" square magnet is 30mm thick (strong enough to hold stuff on the fridge)
or any 5 for $5
or a full alPHabet set of 26 magnets for just $15
shipping is included and you'll likely get a few stickers thrown in too
(let me know which letters you'd like in the notes of your order)
