Most of them are standard airport-sized.
Others differ in dimension but similar size. They also differ very slightly in the type of construction material.
All are clear, plastic, transparent.
Some of them are brand new others, others have been used so they may have a crease or two. And most of them are sealable.
I am loathed to put them in landfill when they could be reused. Thanks
