I wish I could have given a better rated review...

The belt itself is nice and thick like your average black belt can be expected to be. The kanji lettering with the name of the organization is very decent and clearly legible. Sadly, the same cannot be said for the name of my student written in katakana. It looks weird. It's as if one person worked on the kanji and another worked on the katakana lettering. The characters are too close together and it is difficult to see the smaller details in each character. It's like everything is just stringed on and stick together making it particularly difficult to read the name. I really wish I could have gave you guys a better review as I really like the work on thick embroidered colored belts I have seen your company produce for my friends.

What Customers Are Saying About Chokesports

I've always had my eye on RVDDW and Isami brand gear but wasn't sure about how to order in the US. ChokeSports made the process extremely easy and the shipping was amazingly fast. Extreme recommend to anyone on the fence.

Brandon M. Tennessee, USA

Fast shipping. Tee quality and design definitely worth buying. Interesting part was the fantastic services provided by the support team so I could surprise my loved one. Truly appreciated.

Colene T. Perai, Malaysia

I have purchased 4 belts through ChokeSports. Everyone of them was of exceptional quality and the workmanship was incredible! The customer service and ease of placing my order was awesome.

Ken G. Colorado, USA

I'm always happy to open the package to discover another new obi belt. The quality is still the best, delivery time still there, and most important the service is number one. Very dedicated to the client.
