G1 Help Identify These G1 Accessories

[Geriatric Millennial Pony]

Hello pony friends! I need help identifying these mysterious G1 accessories! The first is a white rectangle with a basket weave on the front. On the back it says Mattel Inc 1983 Mexico. (See images for more clarity). The second item is a pink shelf/stairs? On the back it has two sets of numbers MN4972 and PN168342. (See images for more clarity). The final items are three large pink rollers, and I initially thought they were from the Pony Perm Shop, but that set comes with purple rollers, so I don't know what set these rollers go to. Any help or clues you can offer would be greatly appreciated. I'm sorry if I posted this in the wrong section I am fairly new.

If they say Mattel they’re not MLP.
The company that makes My Little Pony is Hasbro, while Mattel makes things like Barbie, Monster High, American Girl, Polly Pocket, and Hot Wheels.
Hasbro employees used to have buttons that said “to H*ell with Mattel,” so I doubt they were sharing accessories

I think the white rectangle might be part of a Barbie white wicker furniture set

Thanks! That is sooo obvious now!

Idk about the other 2, but the white thing looks like part of the Barbie Pretty Treasures picnic basket to me

The pink curved plastic piece looks like the entryway "steps" to the beauty parlor.

The curlers also could be pony, though I'm not sure about that dark pink color...

Sprinkles has curlers like that, but I've never seen them in that color, like CJ Thimble Bright said. Maybe it's another line that used the same mold?

Yep, pic 2 is the steps for the Perm Shoppe. Pic borrowed from MLP wiki cause mine is currently packed up but you can see them there on the bottom left
