The Nintendo 2DS system:
Stylus: The Nintendo 2DS comes with a large, thick stylus that's much like the Nintendo 3DS Xl's default stylus. The stylus works as a sort of virtual "pen" to poke around on the 2DS's lower screen, though the system's tablet-like layout makes it easy to use a finger, too.
A 4 GB SDHC card comes packed in with the system (literally; you'll find the card in the 2DS's SD card slot). The card holds 4 gigabytes of data, including game save data and games downloaded from the Nintendo 3DS eShop.
A Nintendo 3DS AC adapter in included with the Nintendo 2DS and utilizes the 3DS's AC adapter, which charges the device's lithium-ion battery when it's plugged in. Unlike the 3DS, the Nintendo 2DS does not come with a charging cradle.
