Wallpaper straight edge (Bearwood BH11)

MetalWallpaper straight edge 23 ins long . It was bought from QVC and not been used for sometime so would like to pass it on . I remember it was very useful . The label on it says for wallpaper, carpet laying . Not sure what variable cuts with jagged edge means but it says “ perfect fit to ceilings / doors and skirting boards . Please do not message me explaining that just let me know if interested .
