The design of this footbag is pretty unique; it may only be a three-dimensional cube in space but its fourth dimension comes from the function of the bag!
The Tesseract is a 12-panel and one of the more challenging footbags to sew, due to the technique used: you have to connect and fill as you go, rather than filling at the end.
It plays like a regular footbag and is great for freestyle. Stalls really well.
