I'm trying to remember what was in my order from Spingear. I know I ordered the 13.5cm chonkakegoma, which I still can't use, but hey, I have it and it's there when I'm ready for it. I also ordered on the komas, I think. I have two now and I know I got one from YYE. Anyhow, yeah, you order it and 3-5 days later it's at your house thanks to the EMS shipping.
That bearing one looks interesting and is something I will go for after I can do some serious effort on boomerang'ing the koma tops. I just haven't put the effort in. I think that's what I'll be using at the park the next few weeks while the kids do their swim team practice.
