SwitchBot Curtain (U-Rail 3) W2400001 This is a new, unopened item. I purchased two, intending to use them for a double-opening curtain setup. However, one is sufficient for a single-opening curtain, so I am selling the other. There is no proof of purchase or receipt included. Please understand that returns are not accepted for reasons such as the buyer's personal circumstances, except for initial defects. Please purchase with this in mind.
