Keychain for those who don't like the cufflink GE90, which was uploaded first, but who still like the GE90 fan. There is a more detailed description in the cufflink model. This one is larger than the cufflink but has the same thickness of the fan blades, meaning that the fanblades appear thinner compared to the rest of the model. That is why it looks a little more real and better.
the whole on the back is 3mm wide, so even those little steel wire chains or a bigger metal ring will fit through.
IF YOU PREFER A DIFFERENT SIZE FOR THE HOLE OR AN EAR INSTEAD OF THE CYLINDER TELL ME AND I MIGHT CHANGE IT FOR YOU!
