How much does this cost to the nearest dollar?

DjuiinoStar Tungsten Spinning Top (Best Performance Top on Amazon, Best Record 30+ Minutes), Long Distance Runner (15-20 Minutes), Correct The Dynamic Balance of Each Top by Hand
Spinning Top with 3cm Concave glass base and Nylon Stand. For Professional players only, you will still have to practice to get used to the base. After that, you can get longer spin time (refter to the video attached). Our master corrects the dynamic balance of each top by hand; it will cost him about 5-8 hours to make one top like this; and you can count those masters on one hand; if one spinning top can not meet our stand we simply discard it. That's the reasons why it's expensive and why you WON
