Each marble had many small surface chips, some worse than others. These are either factory seconds or the packaging used is of poor quality. Such items must be packed so tightly that they cannot move or collide. If loose, they will bump into each other with rough handling, as with most shippers, where UPSs are the most fragile item, when the box comes in contact with another loading or unloading area. In any case, the seller is responsible for ensuring that the goods reach the buyer safely and undamaged. Note. This product is suitable for small milling jobs.
