While my kids love having a Nintendo DS, it seems that the Stylus gets easily lost. We’ve had to pick up a few replacements since we’ve had ours and they are never very cheap. Right now, you can grab a Nintendo DS Lite Stylus 4 pack for just $1.40 + free shipping! That makes them less than $0.40 each!!!
Even if you do not have a DS Lite, these will work on your unit – they just may not fit into the slot on the back of the case as well as those designed specifically for your unit.
