This a hand made fan made vault boy .... 

U can use it for comic cons ect or for ur game room ect ...

I can add a string and make it into a necklace or a chain and make it into a keychain .... Let me know if not I'm sending it standard keychain 

Measures around 4 by 4 1/2 ... 2nd pic it's with a Xbox one controller showing the size ( controller not included )

Any other figures of anything let me know and most likely it can be done too 

Thanks
