— Before you subscribe

Will these fit my Harb?

Yes. Every core fits every Harb body. Push the old one out with the steel pick, drop the new one in, draw.

How long does one core last?

3–6 days, depending on how often you draw. Swap it when the flavour fades.

Can I change flavours between deliveries?

Any time before your next order ships. Log in, change the mix, save. Same for pack size.

Can I skip a month?

Yes. Skip one delivery or push the date out from your account. Nothing ships and nothing is charged.

How do I cancel?

From your account, in a couple of clicks. No fees, no call, no reason needed.

Is there nicotine in the cores?

No. Zero milligrams. The throat hit comes from plant compounds like menthol and cinnamon bark — not nicotine.
