My toddler throws this cup literally every meal. It bounces. It doesn't leak. It doesn't break. I've bought five. That's the review.

"Finally a sippy cup with no hidden parts to mold. Pop the top off, toss it in the dishwasher, done. I don't know why all cups aren't like this."

"We have one in every color. My kids fight over the teal one. Highly recommend color-coding if you have multiple kids. Game changer."

The Sili Difference

Not All Silicone
Is Created Equal.

Most silicone products use the cheapest grade that technically passes FDA minimums. We use LFGB-certified, platinum-cured silicone, the same grade trusted in medical devices and the strictest food-contact standard on earth. It costs more. It's worth it.

LFGB
German Certified
Germany's food safety standard is stricter than the US FDA. It's the toughest certification a food-contact product can earn.
100%
Platinum Cured
No peroxide byproducts, no fillers, no VOCs. Completely odorless and tasteless. Forever.
0
Toxic Ingredients
No BPA. No phthalates. No lead. No hidden chemicals. Just silicone. Period.

Key Differentiator

The Ring That
Holds Its Shape.

Toddlers don't hold cups gently. They grip, squeeze, and death-clutch them mid-sip. Most soft cups collapse under that pressure, turning a circle into an oval and a sip into a spill. The Oh! Cup has a patented stainless steel ring embedded in the rim that keeps the opening a perfect circle no matter what they do to it.

✊
Grip-Proof Rim
Squeeze the body as hard as you want. The steel ring keeps the drinking opening round, consistent, and easy to sip from.
🥤
Trains to Adult Cups
A consistent circular rim teaches kids to drink normally. No awkward transitions from sippy to open cup later.
♨️
Microwave and Dishwasher Safe
The steel is fully encased in silicone. Seamless, safe, and zero-maintenance.

The steel ring is in every Silikids cup. Oh! Cup, Straw Cup, all of them. It's not optional — it's the standard.

Common Questions

Good Questions.
Straight Answers.

The Oh! Cup and Silikids line is designed for toddlers 12 months and up transitioning from sippy cups. Because kids sip from the rim (not a spout), it trains them to drink the same way they will from adult cups — making that transition much smoother later on. Many families use Silikids well into the school years.
The Oh! Top seats tightly in the cup opening, covered in micro-slits that only open under the light pressure of sipping. This means there's no single spout or straw — kids drink from any point around the rim, any angle, any direction. A stainless steel ring inside keeps the opening perfectly circular no matter how hard they grip or chew on it.
That's the goal — and in practice, yes. Because the entire top is covered in micro-slits, there's no correct angle or orientation. Most kids figure it out within the first few uses. It's also the only kids' cup design that directly translates to learning to drink from open adult cups, since the rim shape and drinking motion are the same.
Yes — GoSili has a large selection of tops and straws. All Silikids cups use the same universal sizing, so lids and straws are interchangeable across the full lineup. You'll never be stuck with an orphaned cup because you lost the lid.
We offer 30-day returns on all Silikids products. If your kid isn't a fan (it happens!) or it's just not what you expected, contact us within 30 days and we'll make it right. Free shipping on US orders over $50.
