There are diffrent names for this trick but because I'm from the oldschool I'm going with the "breakdown" method: it's a Neosonic 12-T1 to fl. ThumbAround Reverse Continuous and can't be learned quite fast - even though it might look a little bit awkward at first and not as fluent (as most tricks and combos in Penspinning).

The Fingerpass is one of the basics tricks and thus one of the first you'll learn. But it's also a great example that being able to fingerpass isn't the same as mastering them. With practice and time you can to it so much smoother and faster which makes it look so much better.

The BackAround to fingerless ThumbAround Reverse Continous is a smooth looking trick/minicombo that can be done continously as long as you want.
