Recently I tracked down a figure I've been looking for for quite some time - the KO MP10U (White Prime or Magnus). The seller was from Taobao and told me it was new and used stock photos. Turns out what I got was a test sample. Not only is the white not as bright as it should be, but the plastic windows are brownish, not blue-ish. I think it's supposed to use the same windows as MP10. If anyone has a junker MP10 or would like to exchange their blue tinted windows for the brown ones or sell to me, please let me know.
Hello, I have a MP-10U for sale, if you are interested. Transformers MP-10U Earth Commander Ultra Magnus Optimus Prime White KO | eBay Outside eBay could be cheaper. Maybe you can decide to re-sell your test shot and take one great specimen? ;-)
