This reel can hold up to 400 feet of super 8mm film and it ha a diameter of about 7 inches.The reel held film from the 1970s and it is in good condition. It features some worn paint and light scratches. It's held its physical shape perfectly without becoming dented, warped, or misshapen. The reel has a gap in the core for easy threading. It will make a great take up reel or a very excellent piece of decor. Thanks for looking!!
