DAZCOS Men's Elastic Adjustable Cosplay Belt, D, One Size

diameter of outside circle? diameter of center disk? width of belt?

Why doesn't this ship to the UK? This is literally the only belt I have found to complete my One Punch Man cosplay.

Im a size 30 waist could make a belt for me for that size?

It says that it could stretch for a waist up to 43", but is there enough give in the elastic so it could fit a waist a little larger than that?
