Tritium capsules...

[Thunderchief]

Being new here I hope to gain allot of knowledge on flashlights as I am a constant user of one everyday.

I have a question though that maybe you all could help me out with. I am looking for a source of Tritium Capsules that doesn't mind selling one or two at a time. I need one that is "teardrop" shaped, about 8 mm x 4 mm. Can anybody suggest a source or if someone here has an extra lying around?

Thanks!
