I have 4 mirrors that can be used as closet doors on a sliding track, One black mirror, and a bunch of 2x4s for a project that I’m no longer taking on.
The black mirror is approximately 56 inches tall 19 1/2 inches wide.
The white ones are 2 feet wide about 78 1/2 inches tall. These are the kinds you use for closets and pantries. They go for around $400 per pair new. BARGAIN!
