 Speed
A standard skate bearing iis rated up to about 24,000 rpm. This is the basic speed rating less 40 percent as the bearing outer ring is rotating. Ours are rated at 49,000 rpm or 59,000 rpm for the ceramic bearings. However, with 75mm diameter wheels, 

 Packaging
Bearings are precision engineered components and secure packaging is important to keep them from being damaged in transit and prevent contamination. It should also be cost effective. You should pay for the bearings and packing charge.
