I got some really helpful rehab stuff I would have never known about any of this stuff myself, idk how I didn't have this stuff sooner. I use the tools every day before I get on the mats and I can say that it really makes a huge difference in my flexibility for sure.
This box was loaded with recovery items that I often want, but never think about buying. I think it's worth the price and I do suggest it for a jiujitsu practitioner.
