Collapsible and expandable strainer / colander - brand “squish”

This is a large used colander / strainer. It collapses flat. It extends to hang off the edges of a sink. It is dishwasher safe and BPA free. There are some signs of wear in the plastic (minor markings), but lots of life left - see example in pictures. There is some discoloration between each collapsing layer (see pictures) but I’m not sure if this is how a new strainer would look. Please let me know if additional pictures or measurements are needed. All offers considered! When possible, I ship in reused packaging ♻️
