Common questions

Sizing, answered

What size holds a standard nitroglycerin bottle?

The Wide Single Chamber Bottle Holder is sized for a standard 25-count nitroglycerin bottle, keeping it sealed in its original packaging on your keychain. If you also carry aspirin, the Large Dual Chamber Bottle Holder adds a second top chamber for it.

How many pills fit in a Slim Single Chamber?

Roughly nine standard tablets, depending on their size. It's the most popular everyday carry — slim enough to vanish on a keyring, deep enough for a day or two of doses.

What's the difference between Slim and Wide?

Slim chambers are 0.5 inches across — ideal for small round tablets. Wide chambers are 0.75 inches across, giving larger or oblong tablets room to drop in and out easily. Both come in single and dual-chamber versions.

Can I carry two different medications without them mixing?

Yes. Any dual chamber holder has two independently sealed compartments, so a morning pill and an evening pill — or two entirely different medications — stay separate and identifiable.

What are the Additional Chamber and Chamber Extension for?

They let you grow a holder you already own. An Additional Chamber threads on to add a separate compartment; a Chamber Extension adds depth to an existing one for a few more tablets. Both match the diameter of your current Cielo Pill Holder.
