The Extend Arms 01 for Revenent Eye upgrade really spice up the whole Frame Arms series. It's good to see Kotobukiya introduce the whole new product to allow more upgrade for exisiting model even works with others. New weapon also included with extra hand parts. But the price does indeed seem higher that cost ¥1,890, which is nearly half the price for one Frame Arms kit.
While the next Extend Arms 02 for Baselard didn't impress me much. You should look out for the upcoming Extend Arms 03 that surely going to be great upgarde for Greifen next year!
