about £1 each Matt
but before you think about ordering any I can't answer your question because I don't have any on my Poles it was Smithy who had some done and he's a member on here, so he's your best guy to ask.
I know the way I use my pole up over roofs and rubbing on guttering etc I doubt if they would last me that long TBH with you Matt.
I've only done the sign writing on the daughters van and added the company details to the tank and backpack, I must admit they do last and when we open the side or back doors of the van and seeing the company details on the tank looks good, it doesn't make you any money because the outside does that but like I say it looks more professional when your doors are open.
I use 5 year vinyl and with experience I know my own old magnetic signs that are still outside on my trailer are over 12 years old and still looking good.
