Need metric feeler gauge set

I have been looking at this one

www.z1enterprises.com/Metric-feeler-gaug...t-25-blades-232.aspx

Is this true metric? Does it have the sizes needed to check valves?

You could order one from Z1, and I love their customer service, but it might be easier to just go down to your local auto parts store. I picked up my feeler guage set from autozone for like $5 and it has both metric and standard sizes listed on each guage. Could save you some time and money.

btw, I use mine to check my valve clearances as well as the spacing on my points gap. It works like a charm.
