Pre-orderUltron 4 Pro By Ba CkBlack body. Blue Japanese engraving. Behind this design — seven years in Asia.
Master Ba Ck didn't copy a specific place. He captured a feeling. That Asian culture, that mindset you won't find anywhere else. He lives in the US now, but this collaboration is his way of paying respect. Everyone will find their own meaning in it.
Ultron 4 Pro gives him freedom: "With this machine, I can do whatever I want — no discomfort, no compromise." Just control, balance, and a big battery.
