Help Identifying and Finding Replacement for Tupperware

[getduckbill]

Hi everyone,

I understand this isn’t the typical type of post here, but I was hoping someone might be able to help me identify and find a replacement for a piece of Tupperware (or a similar food storage container) that I’m trying to locate for a client. Unfortunately, I don’t know the brand or how old it might be.

If anyone recognizes this item or has suggestions on where I might find a similar one, I’d be incredibly grateful. Thank you in advance for your help!
