Large Capacity 280ml for Plenty to Drink

A large-capacity 280ml heat-resistant glass baby bottle. We created this size hoping that babies would drink plenty. While 240ml is popular in Japan, we often get asked by people overseas if we have a larger size. Perhaps babies born recently are larger and drink more.

Commitment to High Quality

Each heat-resistant glass Doctor Betta Baby Bottle is carefully handcrafted by Japanese artisans, so only about 400 bottles can be made per day. Furthermore, strict quality checks are performed, so we can only sell a limited quantity. Midwives even say that glass bottles are the first choice for precious babies, attesting to their safety and luxurious feel.

Beautiful Packaging

The serene image of the ocean is incorporated into the packaging. The moment you open it, marine friends gently accompany you.

Carefully Designed Limited Edition

The gentle shell design is exclusive to the Pearl bottle. The measurements, meticulously drawn to match the illustration, evoke the gentle waves of the ocean. May your baby grow steadily, peacefully, and healthily.

Product Specifications

●Material / Heat Resistance Temperature

Doctor Betta Baby Bottle

Dr. Betta Baby Bottles are designed to make feeding easier for babies. Their unique curve, developed by a pediatrician, helps babies drink in a natural, upright position, similar to breastfeeding.

The bottle's design allows babies to drink upright, which helps prevent milk from entering the Eustachian tube, protecting their ears. This natural posture also allows milk to flow smoothly into the esophagus, preventing aspiration. Additionally, foam rises along the curve, reducing air intake and lessening burping.

●Betta Heat-Resistant Glass Baby Bottles

The functional and beautiful form of the heat-resistant glass "Doctor Betta Baby Bottle" is difficult to mass-produce by machine. Instead, skilled glass artisans in Japan carefully hand-mold each bottle for babies.


"Because it's for babies," any finished product with even the slightest element of concern is discarded without hesitation. We maintain high quality through thorough safety management. These glass baby bottles are carefully crafted with the wish that they will be cherished and used for a long time. Your baby's health and your peace of mind are supported by the artisan's skill and spirit.

●Slim Type Bottle

In addition to the Doctor Betta Baby Bottle's advantages of "peace of mind for ears + preventing aspiration + reducing burping," this type is also slim and easy for both mothers and babies to hold. It is compact and easy to carry, not bulky for outings or storage. Slim type bottles are interchangeable, allowing you to swap nipples between Brain and Jewel.

Brain Nipple: Designed by a Midwife for Chewing Development

Moving from drinking nipples to chewing nipples, this nipple is designed to mimic a mother's breast. It stretches gently like a mother's nipple and fits comfortably in the baby's mouth, encouraging a strong suckling action just like breastfeeding.

Nipples are consumable items

Suddenly switching to a brand new nipple may surprise your baby, leading to feeding reluctance. We recommend rotating several nipples to ensure a smooth transition.
