During summer I was lucky enough to test some great styli for ipad by the Friendly Swede, a swedish company.
They have a great range of size and tips but there is one which I really loved and I highly recommend for every serious ipad artist. It’s their Micro-Knit stylus, which feels so great that every stroke is so smotth, there’s no friction and makes drawing/painting on ipad a great pleasure. Above you can watch a YouTube video and see the stylus in action. Otherwise check the video here!
Micro-Knit styli come in two sizes: Normal and XXL (extremely long but they are perfect balanced in the hand like a traditional brush). The best part is their price. The Friendly Swede styli are very cheap, yet they have great quality and never look cheap. In addition, every pack includes 3 styli and that’s great!
I use a lot of ipad styli for all my ipad artwork you see,
but Micro-Knit is my favourite one. I rarely use my Wacom now because of it.
They also have regular thin tipped styli, which I also like using them for ipad navigation.
So, have a look at their range:
