Mack Sword Pinstripe/Pinstriping Brush 10-1,0,00,000

My first pinstripe brush order.....when they showed up, they were in a bag with a large #30 on it. The card they were attached to said "#30 dagger striping brushes". But they have blue ferrules on them, clearly an indication of a #10 brush, not a #30. They appear to be #10 brushes but since I'm a newbie, time and experience will tell.

excellent

Image depicting product shows 7 brush sizes but product only delivers 4 brushes. TCP Global Corp does this with several of their brush bundles.
