These are "B" grade tops. No number or card will be included.
They spin well, but not quite good enough to meet my typical standards. Each one spun over 10 minutes for me, but picked up some flutter around the 8 minute mark. The flutter in these tops is due to slight variances in the bar they're machined from, which is common in tungsten tops.

One of these has a solid stem (a test top to make sure it was the material and not the hole that was causing the flutter).

Manually machined from a 1/2 bar of W/Cu (Tungsten/Copper) 70/30 Alloy.
Each top will be similar to shown, but some slight variations are possible.
Due to the copper content, W/Cu can develop a natural patina with time and handling.

Satin Finish
0.499 inch diameter (approximate) may vary from 0.495 to 0.5
10.0 grams (approximate) There will be slight variations in weights.
3/32 inch ceramic bearing
Hollow stem.

Spin times will vary based on surface and technique. I cannot guarantee your spin times. Each top will be tested by me. Spin times that are less than 10 minutes (in my testing) will not pass. A faint flutter may be present in the final 10-15% of the spin. This is due to slight variances in the density of the W/Cu rod.
