Glass looks fancy, but it’s a transparent magnifying glass for UV light. Leave a glass-jarred lithium supplement on a windowsill? In 2 weeks, pills darken, and their brain-boosting power drops by half.
Plastic feels convenient, but it’s a leaky umbrella. In humid weather, moisture creeps in—turning pills into sugar-like clumps in 3 weeks. Worst of all? You can’t see the damage until it’s too late.
Made from 99.7% high-purity aluminum, these jars are lightproof curtains. UV, sunlight—nothing gets through. Lithium pills hibernate in darkness, keeping their potency intact for months.
Three layers of defense:
- A silicone “gum seal” that molds to the jar’s edge.
- A spiral lid that tightens like gears.
- A tamper-proof clip that stays shut—even if you drop it.
Tested in 90% humidity: After 30 days, pills stay bone-dry (plastic jars fail in 7).
Weighing 1/4 of glass jars, they slip into bags unnoticed. Built like mini steel helmets, they survive drops and squeezes. No more “oops, my glass jar shattered!” moments.
A Suzhou lithium supplement brand swapped to MERRYNEWON jars last year. Results?
- Complaints about “bad pills” dropped from 15/month to zero.
- 78% of customers said, “Aluminum Jars look pro—we’ll pay more for this!”
- Repeat sales jumped 25%—the CEO called it their “silent salesperson.”

- 100% Recyclable: Remelting uses 95% less energy than making new aluminum.
- Safe & Certified: No BPA, no plasticizers—FDA/EFSA-approved.
- Customizable: Laser-engrave “Take 1 pill daily” on the jar—no more forgotten doses!
Now you know: Lithium’s brain-boosting power is real—but only if your packaging protects it. MERRYNEWON aluminum jars are the “all-in-one bodyguard” for lithium supplements: lightproof, moisture-proof, unbreakable, and eco-friendly.
