Huh, i did not that, so you got unofficial release of the figure or something like that
There is a whole market for garage kit recasts.
What generally happen is hobbyist would create figures using resin (garage kit) and in various events like wonder fest in japan companies would often grant these hobbyist license to sell these kits during that time.
due to it being resin, these GK are often created in very limited quantity (because you can only use the same mold so many times so to obtain these GK, you have to be there and be fortunate enough to get to buy it.
Since these GK are usually very cool (and allow the builder of these kits to mod/paint however they like) and being so hard to get your hands on since you have to be there to buy it, there is a market for ppl selling resin recasts of these kits. There are people who go to these events to acquire kits to sell.
Once some company get their hands on these kits, they create molds using these parts and then sell these recasts. Quality varies, most agree those from thailand are generally pretty crappy (and ebay has a lot of these kits cheap). There are higher quality kits that y ou can buy which a lot of hobbyist enjoy since they can use it to create unique figures to their liking.
Then there is another market that sell prepainted GK. (and while they don't point it out, most often recasts since the original is pretty much impossible to find). Some of these creation can go up to thousands. like yeti arts
shadow x the main artist do wonderful work. expensive as hell. he also has a team working for him and they are usually cheaper to commission.
E2046 is one of the better/well place that sell GK. they also have a line call gathering which they prepaint the figure. It is actually of really good quality too. IMO better than official machine painted figures we buy and relatively cheap. (generally for 1/8 figures, $120-150 shipped.
some of the figures I love. click on the pic to bring up more pics once you click the link.
cost me $340 but check out the pics and the details.
To me, a lot of the official release are quite boring and it is getting to the point that this is where the fun is at. Sure, they are whatever ppl call them but they are far from the $10 bootleg figures you see on ebay. These are higher quality kick ass figures that's more display worthy.
TL:DR ya "unofficial" release
