BOTTLE NIPPLES FEEL JUST LIKE MOM: Quark’s RealFeel nipples are designed to simulate the firmness and texture of a real breast with two distinct, separate texture zones for the tongue and lips, over 95% of babies accept the nipple immediately
EASY TRANSITIONS: Because RealFeel nipples for BuubiBottle are precision engineered to match your baby’s oral anatomy, switching between breast, baby bottles and back is as easy as pie
ANTI COLIC BABY NIPPLES: The unique anti colic valve allows air in towards the back of the bottle- not into the milk – to prevent vacuum buildup, reducing air intake that can cause colic or spit up
4 FLOW RATE OPTIONS: RealFeel nipples come in 4 flow rates to suit any age, developmental stage, or preference. Available in Slow flow (0+ months), Medium flow (3+ months), Fast flow (6+ months), and Flex flow (9+ months)
100% BABY SAFE MATERIALS: Made from medical-grade LSR silicone. Quark baby products are made with ZERO bisphenols, ZERO phthalates, ZERO lead, latex, and other toxins

Good quality
No problem
Flow
One teet would not allow milk to flow through. Baby tried feeding for a while before I noticed milk was not passing. The other works fine.
Worst
I was charged a crazy amount for shipping my baby choked on them and they refused to let me return them. Avoid at all costs.
Kid loves it but its bottles are plastic and over time warm liquid deforms it
We love our quark bottles 100% recommend them
I love these bottle nipples! They fit every bottle I own and are perfect replacements.
