Thanks to the seller for a very fast shipment and good packaging of the product. And AliExpress for fast delivery. Everything came whole without damage. In just 8 days, the parcel arrived in Israel!! Great speed!! Suitable burs. They work. The coverage is uniform. But I expected more abrasion resistance. They wear out too quickly when working on glass. However, for this price... I think it's okay. I recommend both the product and the seller!
all ok
