I assume you're asking because there's a reference to it in the manual. No, there's no SD card in the kit, at least that I found. The files are on the google drive linked from the FT product page. Until you do get an SD card, you can print via USB port with Pronterface or (I think) Repetier.
As far as the actual SD card product, they're pretty standard. Get a regular SD card as opposed to a mini- or micro- SD. There are speed and capacity ratings on the card and your printer will not need the higher rated speeds, though it won't hurt. Something like this is fine, although way more capacity than you'll need: SanDisk SD card from Amazon
You'll also want an SD card reader if you don't have one, so that you can write the files onto it from your computer. Again, you don't need the fastest.
