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. See them side by side.

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.
