A sealed steel chamber holds more than pills.
Every Cielo is machined from solid stainless steel and closed with an O-ring, so whatever is small enough to fit stays dry, clean and on your keys, whether or not it is medication.

Hearing aid batteries and parts
Spare cells, wax guards and domes, sealed against moisture and easy to find when one quits.

Earplugs
A pair of foam or silicone ear plugs for the range, the shop floor, a concert or a loud flight.
Earplug cases
Migraine rescue medication
A triptan, or a triptan and an anti-nausea tablet kept apart, on the keys you already carry.
Migraine pill cases
Nausea and motion sickness

Nausea pill casesSome things never get a case designed for them.
A Cielo will hold a wedding ring through a swim or a workout, a day of vitamins and supplements, one allergy tablet, or the single emergency dose you would rather not be without. None of that needs a purpose-built case, just a chamber that seals and a keyring you already reach for.
The chamber is half an inch or three quarters of an inch across depending on the model, machined from solid steel and closed with an O-ring, which is why the contents come out as dry as they went in.
Not sure which size you need?
Every holder is waterproof, machined in Minnesota and guaranteed for life, so the remaining question is how much you want to carry at once.
