I buy mine in a pack of 100 for £34 from Germany think they are through eBay they are free delivery and they made by areeda or sumin will find my last order I bought but I am very pleased with them and I have tried about 10 different makes and I'm gonna stick with these as they are cheap and last very well. But like all these thin discs if you abuse them they don't last and I will never buy any blackspur ones or silverline ones again as I have had a few snap or break up while cutting and I have the scars and rips in my overalls to prove it.
