Honest feedback shared by parents like you.
Saige Lee
Magic happened for my son! This cup has worked great. My son is two and he still had not figured out how to drink from a straw. I've tried so many cups and non worked for him. Something about this one inspired him to figure it out and within a few minutes, he was doing it!

I have been looking for this one everywhere in the U.S. nd it was sold out or unavailable. I was so excited when I found it here on Onzenna! My daughter LOVES all her Grosmimi cups and this was more for me cause the design was so cute. Plus the flip top was just perfection!
Rose Levy
Alpremio has been a game changer for us. Feeding or just relaxing, my baby looks so comfortable on it. Ot's durable, soft, and feels like it's designed with real care for babies, and it's so easy to clean. Knowing my baby is safe and happy makes Alpremio worth every penny.

This kids’ water bottle is so well designed! The easy drink spout has a small hole that controls the flow, so water only comes out a little at a time—perfect for toddlers. It’s practically spill-proof thanks to the cork inside, and the cute design and colors make it extra fun. The handle makes it easy for little hands to carry, and it’s super easy to wash, which is a big plus for parents. My toddler loves it and actually enjoys drinking from it!

Always in Korean
Always by your side, through every stage.
Curated products and practical advice you can trust.
Questions parents actually ask.
What does Onzenna actually sell?
What does Onzenna actually sell?
Curated Korean baby essentials — PPSU cups and bottles, silicone mealtime gear, bamboo bath, organic snacks, infant skincare. Every brand we carry was vetted before it earned a spot on the site. We rejected hundreds.
What does "curated" mean here?
What does "curated" mean here?
It means we read the spec sheets. We check the certifications. We test the products on our own kids before listing. If a brand fails on materials, manufacturing transparency, or third-party testing, it doesn't make the shelf — even if it sells well elsewhere.
Why Korean brands specifically?
Why Korean brands specifically?
Korea's KC certification requires third-party material testing on infant products before they can be sold. The U.S. FDA framework for infant products is largely self-certified by manufacturers. Our category specialists like Grosmimi have decades of R&D on infant-safe plastics.
What is PPSU and why do you prefer it?
What is PPSU and why do you prefer it?
PPSU is a high-performance polymer engineered to withstand repeated heat sterilization without breaking down. Standard polypropylene (PP) bottles release microplastic particles during hot-water preparation (Nature Food, 2020). Our bottle and cup brands use PPSU instead. We don't sell standard PP for cups or bottles.
Are these products safe? What certifications?
Are these products safe? What certifications?
The brands we carry are KC-certified (Korea's third-party infant safety standard). Many also hold FDA, LFGB (EU), and BPA-free designations. Specifics live on each product page — we list what each brand has been certified for, no more, no less.
Where do you ship and how long does it take?
Where do you ship and how long does it take?
We ship across the United States. Free shipping on orders over $75; flat-rate shipping below that. Standard delivery is 3–5 business days within the contiguous U.S. once your order ships. You'll get a tracking link by email when the label is created. International shipping is not available yet.
What's your return policy?
What's your return policy?
Unopened items can be returned within 30 days. Customer-remorse returns carry a 15% restocking fee and a $7.99 return label; defective or incorrect items are always free to return. Some items (Alpremio, Comme Moi, food products, gift cards) can't be returned — see our Refund Policy for details.
Are products authentic? Do you import gray-market goods?
Are products authentic? Do you import gray-market goods?
Every product is sourced directly from the brand or its U.S. distributor. No gray-market, no third-party reseller stock. If you got a product that doesn't look right, tell us — we'll replace it and investigate.
