McDonald's "Open 24/7" Feather Flag is printed on durable all-weather 200 denier nylon. You can purchase these in sizes 7ft - 17ft with a ground spike or with a base and water ballast.
Single-Reverse is how most flags are made, it's standard and means that the flag will read through on both sides with one side reading how you see, the other reading the reverse. Double sided will make it read the same from both sides.
These are proudly made in the USA.
