Does anyone else on here own a Format:C Gen 2 **Flat Face** Proto? On the one I have here, one side has a flat rim: ![](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/6/8/8/688c0e813b42bf438f7f6dd81e8e0eb572384509.jpeg) And the other side is angled inwards, like the retail version: ![](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/3/8/2/38287ef32212252babed00a907bcc5810c85623f.jpeg) This is really strange. Are they really meant to be asymmetrical like this? ---

It is a proto, and they may have been prototyping that feature. Protos aren’t meant to be perfect they are for actualizing ideas and concepts prior to production. So yes It could be normal and unique to that prototype ---

In this case, I think an oversight happened at some point. Only one of the protos is described on the Lab Experiments page, but it is very specific about what to expect. ---

Well _that’s_ interesting. I bought this one from its original owner @Zeek95. @da5id any clue what’s going on here? (Check the first post) Zeek’s friend also has one like this too apparently? Like, did the halves get mixed up with a production Format:C Gen 2 when you guys were assembling them? There are only 8 of these things in the world so it shouldn’t be too hard to get to the bottom of this. 😆 ---

By any chance, have you contacted OneDrop directly? Have you contacted the exact people that would have the exact answer you seek? Just curious. Because more often than not, they have a fairly good idea what they’re doing. ---

There were three different prototypes. It looks like we made a mistake in assembling that one. I guess it’s a one of kind 🙂 ---

Or not. Sometimes there are odd numbers of halves. More likely this is the only one. ---
