Strain your food without ever having to transfer it from the pot you use for cooking! Each pot fits a number of different lid sizes. The first strainer comes with an attached strap with grips at varying lengths that attach to the opposite end of the pot. The other one is an accordion-style lid, folding to fit different sizes and snapping into place using grips on the back of the strainer. Each strainer is made of high-quality BPA-free plastic. These durable lids can be used over and over and washed easily with soap and water— even put them in the dishwasher!
