After spending an hour on the internet looking for Emery Cloth, with 99% of the sites I found offering me Sandpaper. Cannot web site makers tell the difference between Cloth and Paper yet? (rant over)
I came across Redstone Abrasives and they understood that Cloth was Cloth and Emery Cloth was different from Aluminium Oxide paper.
The site is easy to navigate, they have an extensive range of abrasive products from a 50M roll @ 115mm wide to Third Sheets @ 230mm x 93mm and much more between. Never have I found such a comprehensive range of products at an online site, with such an easy ordering system.
The best parts: Not only did they beat every retail outlet (such as tool station and Screwfix) they also halved the cost from other companies supplying in this field.
Placed my order on Tuesday and it was delivered on Wednesday morning, less than 18 hours from order to delivery. Now that will take some beating. Well done Redstone.
