Thanks to BuDn3kkID for starting this poll! We've contacted the vendor on your behalf and they've made the ForeverSpin Titanium Spinning Top available.
Hey guys, I wanted to let you all know that we've reached out to Forever Spin to see if we can work together to get their perfectly balanced spinning tops on the site. I hope to have good news to share with you in the near future.
For the record, as of today (29th June 2014 GMT+8), I own all the Japanese-made spinning tops and the Spinny Doo. The others are produced via crowdfunding-site Kicsktarter (and Indiegogo) and are in the process of fulfillment, thus I will be getting them soon.
