This product is great for shipping your animals if you are looking for a cheap container that does the job during shipping but does not show off the animal inside as clearly as a SOLO container. Save a few cents on a container that still secures and allows your animal to be seen during shipping. This lid fits all 4.5" Slightly Opaque Pre-punched Deli Containers (8 oz. to 32 oz.) DON'T FORGET TO ORDER A CUP TO GO WITH EACH LID!
