I got my first copy of the MC Model Gundam Wing Custom Snow Prelude.
Mine has a couple paint issues, the skirt looks like paint rubbed off from friction on the surface and one of the edges on the torso also suffered from paint rub.
I blame the poor packaging on these issues I have. Your mileage may vary. These can be fixed with a brush and some color matching.
As Indicated in the review video, the thigh portion of the knee pads aren't attached to the lower portion out of the box. Take care and slowly lift the sides of the pad to get the pegs seated to the lower part.(https://youtu.be/1Ugi-HJBZqQ?t=63) As seen at this timestamp in the video.
The "stand" adapter (connects to tain area of the suit) may not hold the figure securely. Lift the skirt up and tighten the screw used to assemble the lower torso. It is behind the left leg.
That is all I have to report about this figure so far, I am still trying to figure it out. I have another in the mail, maybe I will have better luck with the paint on the next one. I will upload some photos in a couple days.
Overall, I recommend it if you missed out on the official one. It is fiddly to handle but that comes with the territory of any winged figure with so much going on. Official or KO.
It does not come with instructions, refer to the reviews/overview videos out there to see how it all goes together.
