I received the Genos arms and i am satisfied with how they look, however they could definitely be a little more direct with size or offer a sizing chart The arms do not fit me at all, im in pretty good shape, so ill likely have to cut/alter it and get some velcro to custom fit them on my arms. The only piece that fits fairly well is the shoulder piece, and the gloves. This will still be a great cosplay to present at my next convention but definetely be aware that unless you're 125 lbs, you might have a hard time wearing this out the box. One size does not mean they fit just anyone.

Received these today after they were in shipping limbo for 20 days. Not the fault of miccocostumes but I wish there were additional, more reliable shipping options. I ordered from the US- tracking updates are spotty on First Class International mail and reports for missing mail can only be made to USPS after 45 days. I gave up on these arriving before my deadline but was pleasantly surprised to finally see the tracking update (only updated once they arrived at my local post office) Because these came only two days before my deadline I was really hoping they would be wear-ready. They are not. The color/spray paint job is poor and spotty. Dark gray in parts that fade to a light gray and splotches where the paint was dripping as it dried. The quality Otherwise, the product came as pictured. The magnet that attaches the shoulder piece is strong. Foam is good quality. "One-size fits most" not necessarily true. Be sure to measure before ordering as these are on the small side.

The Genos arms by miccostumes are extremely high quality. I will start out this review by saying if you are looking for a pair of high quality Genos arms that are not only accurate, but durable, then you've found them. The construction is great, they are comfortable, and the only piece that may need tweaking are the gloves. Absolutely worth the price for any Genos cosplayer.
