As a disclaimer, please excuse the quality of my pictures as the only camera I have is my iPhone. When I got my first two Dr. Wu products and saw pictures of the upcoming FE Prime Sword re-casts, I was a bit worried, as the previous two were actually made of resin. These, however, are not! I was super relieved. To prove the durability of these things, I accidentally dropped on a hardwood floor and there was no damage. Their silver paint is quite nice too, similar to the gun recasts'. With an actual firm sword, Optimus finally has a chance against Megatron! And yes, they do fit the PRID Prime just fine. Perfect replacement for the retail one. (Also, didn't have a stock PRID Prime, but I have my custom PRID Nemesis Prime) In conclusion, these are probably my favorite Prime Wu set I own. The durability of these really gets my hopes up for their upcoming products. If you're interested, but don't need two, I recommend getting at least one to replace that bend-tastic retail one.
