All sellers and buyers must use PayPal Goods and Services as the method of payment. Any other method puts your money at risk. Do not send Steam codes, Amazon or other gift cards, bank transfers, or any other risky payments, as you will have no protection from losing your money. Do not accept excuses about someone's PayPal account not working. Scammers have used these tricks before! Please message the moderators immediately if anyone asks for payment by any unapproved method or is making excuses for why they cannot use PayPal, as these requests are strictly against our rules. *I am a bot, and this action was performed automatically.

Sadly shipping costs more for private individuals for ink, unless it’s under 1lb total. You can even get free Prime shipping from Amazon, which sells both of those inks.

I've successfully avoided ordering from Amazon for 6 years & would like to keep that streak going! thanks for the suggestion, though. shipping with things like Pirate Ship etc. is pretty cost-effective for individuals & I figured it was worth a shot at least in case, as is very often the case, someone was doing a downsizing. I've seen these inks come up in the past, I've just missed them. shrug.


If you can use cartridges Office Depot usually has Serenity Blue ones


unfortunately this is for some vintage lever-fill pens, but good tip regardless, thanks!!
