This is a Type-C port protection adapter purchased from a Chinese shopping site. It's compatible with MacBooks and other devices (see the 4th photo). The design combines two Type-C ports into one, protecting them while also allowing for connections and expansion. The brand is "HAGIBIS," and I think the quality is good. I bought two and have one for sale because I bought too many. It's a new, unused item, but it has been stored at home after purchase. *Please refrain from purchasing if you are concerned about minor details due to it being a foreign product. *The condition description is based on the seller's subjective opinion.
