PureSip is the only training cup built to eliminate microplastic exposure — the hidden danger in your toddler's plastic sippy cup.
Research from Trinity College Dublin found plastic cups shed up to 16 million microplastic particles per liter into your child's drink. These particles don't pass through — they accumulate in their brain, organs, and bloodstream during the most critical development window of their life.
PureSip is different. It's not "safer" plastic. It's zero plastic.
Why It Works:
- Medical-Grade 316 Stainless Steel: The same steel surgeons use for implants that stay inside human bodies for decades. Biologically inert — doesn't shed, corrode, or leach.
- Medical-Grade Silicone Lids: Made from silica (sand), not petroleum. The same material hospitals trust for heart valves. No shedding, no degrading.
- No Hidden Chambers: Unlike "spill-proof" cups with mold-breeding valves, every component of PureSip inverts completely for cleaning. If you can see it, you can clean it.
Zero plastic. Zero microplastics. Zero toxins. Mathematically zero.

We know you've tried other cups before. We know about your graveyard of scratched, stained, moldy plastic sippy cups.
That's why PureSip comes with a 60-Day Money Back Guarantee.

"The Only Training Cup I Recommend to Parents"
Dr.Natasha Collins | Pediatrician
"After the Trinity College microplastics study, I threw out every plastic cup in my practice. PureSip is the only training cup I now recommend — medical-grade steel, medical-grade silicone, zero plastic touching your child's drink. This is what safe looks like."
Why 11,000+ Parents Threw Out Their Plastic Cups
Research from Trinity College Dublin found plastic sippy cups shed up to 16 million microplastic particles per liter into your toddler's drink.
These microplastics don't pass through — they accumulate in your child's brain and organs. Studies link them to:
❌ Developmental delays
❌ Weakened immune systems
❌ Hormonal disruption
❌ Constant sicknesses
And "BPA-Free"? They just renamed the chemicals. BPS and BPF are just as toxic.
Your toddler's developing body can't process these toxins the way yours can.
Finally, A Cup With Nothing to Hide
PureSip is made from medical-grade 316 stainless steel — the same steel surgeons use for implants that stay inside human bodies for decades.
The lids are medical-grade silicone — made from sand, not petroleum. The same material hospitals trust for heart valves.
Zero plastic. Zero microplastics. Zero Lead. Zero toxins.
☑ 100% Microplastic-Free & Toxin-Free
☑ Medical-Grade 316 Stainless Steel
☑ Medical-Grade Silicone Lids
☑ No Lead, No Rust, No Metallic Taste
☑ Dishwasher Safe
If it's safe enough to live inside your body, it's safe enough for your toddler's cup.
One Cup From 6 Months to 3 Years
PureSip comes with both lids included — adapting to every stage of your toddler's development.
SIPPY MODE (6+ months)
Where it all starts. First sips on their own.
STRAW MODE (12+ months)
As they grow. Mess-free and confident.
CUP MODE (18+ months)
When they're ready. Full transition to open cup.
Unlike plastic that cracks, stains, and gets chewed up — stainless steel lasts forever. This cup will still look new when your toddler outgrows it.
Leak & Toddler-Proof — Without the Mold Trap
Most "spill-proof" cups use hidden valves that trap moisture and breed mold — black mold growing in the exact place your child's mouth touches.
PureSip is leak-proof without hidden chambers. Every component inverts completely for cleaning.
If you can see it, you can clean it. No surprises.
And yes — it survives toddler tantrums. Throw it, drop it, bang it on the highchair. The lid stays sealed.
The Purity of Glass. Without the Shatter Risk.
Glass is pure — but toddlers drop things. One drop on tile and you're rushing to the ER.
And most daycares ban glass entirely — forcing you back to plastic anyway.
PureSip gives you the purity of glass without the danger. Medical-grade steel is functionally indestructible. Drop it, throw it — it survives. Your child stays safe.
Daycare-approved everywhere. Your protection doesn't stop at the front door.

One Cup. 3 Years. Zero Replacements.
Most families replace plastic cups every few months — chewed up, cracked, stained, or moldy.
At $10-15 each, that's $100+ over 3 years on cups that poison your child the entire time.
PureSip lasts from 6 months to 3+ years. One purchase. Zero microplastics. Zero replacements.
The durability means it survives multiple kids. Hand it down — medical-grade steel doesn't wear out.
The real question isn't whether you can afford PureSip — it's whether you can afford to keep using plastic.
