Magnetstreet- magnet STD's- ORDERED!!!!!

so we ordered our STD'S!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! SOOOOO fricken excited!!!! we ordered the photobooth 'made for each other' magnet!!!!!

just one question to those that ordered the magnets.
is the envelope they give you bigger then the magnet? it looks like it on the website. i didnt order the sleeves or whatever they are called because i wanted to put them in the e-party thank you cards. but then we couldnt find any thank you cards that would fit the magnet. (i did find one, but they were baby shower thank yous, and there were no other ones)
so i was wondering if the thank you card would fit in the STD envelope??

thanks!!!
