OK guys FYI. First pictured pen is Dayacom Citizen $10.52 each in MOQ of 500 pieces in Rhodium Rollerball shipped. Drill bits 12.5mm, 27/64 and tubes are the same as Jr. Statesman.
I'm guessing, but did not ask, that Ti, Black Ti and 10K gold will be a little less money.
If you've never dealt with Dayacom you might want to find someone who has to handle that end of the buy. I can help you here, but only with the actual transaction with Dayacom. I don't know if they are still as fussy, but it used to be they would only deal with businesses on the wholesale side of the house.
If you get to 375 Smitty's Pen Works will finish your order. You'll need to get a group buy approved and set up in accordance with the IAP Group buy rules and you'll need a coordinator. As a vendor I can't do that (and wouldn't if I could).
