I got them off eBay. Pretty sure they are TBs, but I thought TBs counted as GRs.
Might have just been the few listings I'd seen of the colorway, but they had things like "rare," "unreleased," and "sample" in the listings and I'm not sure if that's true so I figured I'd ask.
TB's can be unreleased or they can be GR's. Most of the Kobe TB's that were sold at retail were sold through Eastbay and/or the Nike web site.
TB's that were not released to the public generally find there way to the outlets. A lot of KOBE TB colorways were made for special events or college /high school programs.
Many Kobe TB's that were not GR's will often have a 9999999999 on the label indicating they were not intended for the public. They often do not have that rip off perforated retail price on the box either.
At times you will see Ebay sellers claiming the 9999999999 tagged Kobe's are Promo Samples or Player Exclusives which is absolutely not true. It only means that Nike didn't issue an identifying number for that particular item.
Next time you are in one of the outlets and you see a Kobe TB have a look at the box and the label.
In fact my outlet in NJ (Jersey Gardens) is presently selling a White/Grey Kobe X TB with the 99999999999 in the label and no retail price. They had well over a hundred pairs about two weeks ago and they still have pairs as of 2 days ago.
Anyway, I hope that helps explain the TB Kobe's.
