I have these balls which are surplus to requirements, you are buying all 4. These are Dukes Royal Crown balls (X-grade) which are top top quality balls normally used in high level premier league games. They are only x-grade due to slight marks to the leather that are barely noticeable but at £50 a ball for the non-x grades these are a bargain. I’ve used these myself and they are excellent, they keep their shape and you can polish them properly. Any questions let me know, thanks for looking ????
