Specs: Capacity ~7 Nitrostat · Inner diameter 0.2" · Total height 1.4" · Weight 0.3 oz (steel) / 0.2 oz (titanium) · Stainless steel or titanium · Made in Minnesota, USA Nitroglycerin pill holder FAQ How many nitroglycerin tablets does it hold?Up to about 7 Nitrostat tablets — or roughly 2 of the slightly larger Lifestar tablets. The inner diameter is 0.2", so exact capacity depends on your brand of nitroglycerin. Is it really waterproof?Yes. A rubber O-ring seals the cap so your tablets stay dry through rain, sweat, and hand-washing — even an accidental trip through the wash. Keep the cap closed to maintain the seal. Stainless steel or titanium — which should I choose?Both are equally waterproof and guaranteed for life. Stainless steel is our classic at 0.3 oz; titanium is lighter at 0.2 oz and a touch more premium. Choose by feel and weight. Will my nitroglycerin fit?This holder is sized for loose nitroglycerin tablets, not the pharmacy bottle. To carry your nitro in its original bottle, choose the Nitroglycerin Bottle Holder. To carry nitro and aspirin together, see the Large Dual Chamber Nitroglycerin + Aspirin Holder. Not sure which fits your nitro? Compare all three nitroglycerin pill holders. Can I keep it on my keychain every day?That's exactly what it's built for. Machined from solid stainless steel or titanium and guaranteed for life, it rides on your keys through daily wear so your nitro is always within reach. Where is it made?Every Cielo nitroglycerin pill holder is machined in Minnesota, USA — and 5% of every sale funds autoimmune disease research.
