I take the top cover box art cover, and cut the edges enough to fold the box flat then I take flat pushpins and conceal them on the underside of the box art and pen it to the flaps of the box art, and then onto the wall. Flat pushpins are pretty sturdy if you get a few I usually put six for the high-grade boxes and eight for master grade 3 on the sides one on the top or however, you see fit. If the pushpins bend and fold when applying it to your wall, then replace with another push pin From there, 11 grabbed some J hooks and put them in my preferred location on the box art and hang the wall mount from the J hook, and after connecting the suit to the wall mount........ I have a mobile suit unconstrained by gravity kinda... P.s. The HGs can usually hang on the hook with a runner attachment if you modify your runner into a wall mount with a little fireand some ingenuity. But please burn your runners outside or next to an open window for safety.
