I bought this to make stabilizers for the high power booster stage L2. I have bought similar items from Chinese sellers on eBay in the past and had to wait many weeks for them to arrive in the mail. It arrived on time. The surface is immaculate; The edges are smooth, square and regular. As expected, he is very strong. I will have no hesitation in buying from this source for my next project. Other reviewers of similar carbon fiber tops have complained that they're a few millimeters narrower than advertised. It's the same here, so consider the "nominal" size. Also, the thickness is listed as 2.5mm, but my piece ranged from 2.60mm to 2.64mm. It doesn't matter to me, but be aware if you want exact dimensions.
