Why?
Because they're all the "non Nintendo Selects" edition, plus four of them have the hacked save state for loading CFW. I intended on selling them after the injections, but then I just ended up keeping them for each of my 3DS consoles (2DS/3DS/3DSXL/N3DS/N3DSXL) because if there comes a time to sell my 3DS consoles, it's somewhat (but not completely) beneficial to the firmware.
nah no
And yes, which we can do this all day if you wish...
