Nice! Are those the Johnny Lightning Cases?
It looks like this is the case Jeff uses. Correct?
Yeah, I'd very much like to know what types of cases those are as well, especially since IG-88 can actually stand up in those! Give me details, like where you found them, how much, etc. They don't look like they're individual pieces. Do they come in sixes?
Yes indeed! The Johhny Lightnig Interlocking Showcase. Each case has 6 spaces and they can interlock to form different arrangements. While doing my research, I came across many places that sold them:
$5.99 at TRU
$6.99 - $7.99 at "Collector" Shops (Hub Hobby, Model Shops, etc).
$7.99 at Target (costs more because the Target version comes with an exclusive JL car).
They are always in the JL section of the store, but I haven't seen them at Target since Christmas. I have seen them restocked at TRU recently though. I did some checking at JoAnn and Michaels craft stores, but never really found any case that worked for the space I had.
I actually got mine by ordering a few from a local hot wheels dealer guy (4 cases for $20), then managed to snag a three more after Christmas at Target (only $3.84 on Clearance). Each of the Target cases actually came with a Johhny Lightning car, but I just gave the 3 cars away to the nephews. They don't care that they are "fine die-cast replicas" just that they are cars.
The only Kubrick I have that didn't quite fit was the Carbonite block, as you can see in the picture, it is kind of tilted to get it to fit in the space. Otherwise, everyone else (Astromechs,/IG-88) fit nicely.
