This is a PRUSA MK3S+. (Made by the original manufacturer, PRUSA of the Czech Republic. Not a clone.) The included genuine build plate is unused. After a simple cleaning, it has been initialized and calibrated. I adjusted the Z-axis and printed a 3DBenchy. The 3DBenchy in the photos was test printed with PLA after calibration. (The plate used was for testing, and the included unused plate was not used.) I was using it until recently, so it's a used item, and its operation has been confirmed. I will ship it via Takkyubin (160 size) with shipping costs covered by me. I have multiple units available, so please let me know the desired number if you are interested. A PRUSA-designed filament guide has been printed and added to the filament holder. Two spool holders (silver tubes) are also included. A silicone sock is attached for stable printing.
