Mini Nuns are actually paracord Thumbchucks or mini nunchucks. They operated similarly to a balisong but without any of the danger.
To play simply lay the Mini Nuns on you hand and hold on one end while pinching the other side with your thumb. Try and swinging it around and grabbing it on the original side by side grip again. There are endless tricks to learn and many of the tricks that work on balisong transfer nicely.
Note: Colors may vary slightly from photos.
