They are $40 shipped in the CONUS without a tip, $45 with. Payments via PayPal G&S preferred.
These tops are printed in 95A TPU, which has a little bit of give to it. You can squish the material in between the widest point of the top and the tip.
Specs (with plastic tip installed):
* 89.5mm tall
* 67.4mm wide
* 87.5g
The first top is blue.
The second is red. It has a tiny rub mark from my test throw going awry
. I have attempted to capture it below. 
Private message me if you have any questions, comments, or want to purchase.
