Product description
Step up from baby bottles!
The "Sippy Cup Circus" you want to use after graduating from Betta baby bottles
From around 7 months, when your baby is used to solid foods
Born from requests for a larger capacity, this is a 300ml sippy cup.
The size is easy to use not only during the baby’s weaning period but also as they grow.
Customize according to growth and situations
Equipped with two types of drinking spouts, "straw" and "direct drinking," for long-term use. You can customize the sippy cup by simply swapping the top lid parts, allowing you to switch according to growth and situations. Recommended for adults too, like moms, dads, grandpas, and grandmas.
This 300ml sippy cup is made from biodegradable plastic with P-Life added to polypropylene. P-Life is a safe additive that promotes microbial degradation of hard-to-decompose plastics like polypropylene in natural environments.

What is Betta's sippy cup "Circus"?
The design is inspired by a "circus" full of fun dreams. We focused on creating a design that sparks kids' imagination every time they use it.
From a baby bottle
For stepping up
Once they master drinking well with a straw, transitioning to drinking from a cup becomes smooth.
"Drinking by themselves"
Training
When your child can hold the sippy cup and drink well by themselves, the next step becomes even more fun.
On the go
For hydration
A sippy cup that you can quickly give to your child anytime, anywhere is an essential item for parenting.
Slim shape
The slim shape is convenient for carrying. Easy to hold even for small hands, it fits in backpacks or mom bags without taking up space and can be quickly taken out.
Matte texture
The texture is matte to prevent slipping even for small hands. We focused on a polygonal finish.
Easy-to-hold straw
The tip of the straw is "plump," making it easy to hold in the mouth♪ Smooth and gentle on the tongue.
One-touch open
The straw cap is easy to operate with one touch, even for small hands!
Measurement marks inside
The inside of the bottle has measurement marks so you can measure the amount you pour.

Leak-resistant, secure design
"Leak-resistant design" is also a key feature.
* It may leak if turned upside down or shaken.
