Tupperware Vintage Bread Keeper With Lid 606-1 Stained With Marker

I got this from an estate sale and it is stained with permanent marker where someone wrote their last name. I find the lid to be a little tricky to get on, which makes me wonder if it possibly got ran in the dishwasher.

I’ve tried to price this reasonably given the heavily used condition and yellowing, especially on the side.

Offers welcome!
