I like the larger XL pen-style stylus and wanted one for my 3DS, and also to have some extras for when they inevitably get lost. The styli in this set are not quite identical to the originals, however. For one thing, the large pen-style ones have an actual clip on the other end, rather than just the stylized appearance of one, as the OEM ones do.
The smaller styli (that can be stored inside the DS) are NOT the same length as the XL originals. They are, in fact, the same length as DS lite and DSi styli. They fit perfectly into the DSXL's stylus slot, however. It's not a big difference (half an inch, maybe?) but I just wanted to make it clear to anyone who might think they're getting the hard-to-find XL-length stylus - that's not what it is.
You get 3 sets, as pictured, packaged in a clamshell that you'll probably need scissors to open. I paid $6 for this, not a bad deal at all, compared to most places that are loathe to sell you a replacement DS stylus without ALSO selling you a screen protecter, game cases, and other silly unwanted accessories, for $10 or more.
