I recently got three of the 50th Anniversary of Lucasfilm TVC Tusken Raiders (VC 199). And I'm glad that Victoria from
Victoria's Cantina made me aware of the one issue with this figure and Tim from Bossk's Bounty
made a review.
You need to be very careful with the hand joints of this figure because they even break quite easily. I mean it barely moves and you can feel that the shaft inside is bending from the beginning.
Also the head is very tight on that neck socket. Both issues might be fixed with hot air until you get it into the position you want. I suppose the reason for this issue is found in the tooling and the used dimensions for the forearm and hand. The shrinking behavior of the plastic might've been calculated wrong. Just my guess...
