All the 12g kits are currently sold. I'll work on ordering more valve stems if there's interest. I also want to make sure everyone is happy with the o-rings and seals provided so please let me know what you think when you receive your kits.
Note: While I would love to take credit for his work, I am not associated with Mad Customs!
