OK then - it's done. Sample Packs are now available. One of each type, in both black and blue. Each type is in a sample Retail Pack so you get to see those as well, and you can get the "full picture" Price paired to the bone. Free UK P&P.
Go to the "Buy & Sell" forum for the link.
Whilst I might make them available outside of this forum in the fullness of time, they won't be the same price and they wont include free p&p, so this sample pack, priced how it is, is for members of penturners.co.uk only. The only way you can access the page to order it is from the Buy & Sell forum.
I'm grateful to Buckeye for the suggestion. Thanks Peter.
