Indicative Pricing With Allowance for P&P

So far these is only a need for two of these and you can order two via the link above for 75p each. You might as well buy a few more for little extra cost in case we use them again. As a compromise on indicative price I've suggested 50p each.

Allen key head looks good too. Stainless steel or black is nicer but costs more.
