Last night I came across a black Gear Cube which was fully stickered, including the inner edges.

Now I really enjoyed this puzzle, and would love one of these for myself, however I checked in the usual places and I can only seem to find it without the central edge stickers applied.

Is there anywhere I could order one with the extra stickers, or would I have to order the stickers from someone in addition?

I don't know if you can get it with those center stickers already applied in any store, but Cubesmith does sell Gear Cube Stickers that have the inner edge pieces.

Thanks for that!

I think I'll have to order the cube and stickers separately and sticker it up myself.

It seems a bit of a shame to me that they aren't originally sold with the inner stickers.
