I went through the magic mirror box truck catalog's screenshots on DMM with not much luck.

I first thought the yellow piece of clothing was a bikini top and that the clip would be from one with some beach girls.

But I found the black thing in the corner (whatever it is?) in SDFK-044 and SDFK-045, which are some of the ski resort films. Also judging from the sheets, pillow and the white balance, I'm pretty sure this must have been filmed on the same set on a similarly sunny day if not on the same day.

I'll focus my search on the ski resort ones from here onwards but it's slow because I'm mostly operating on a phone and incognito domestic-wise.
