RiseCub Pure
The Glass Baby Bottle That Puts Your Baby First
“Finally, a truly plastic-free option I feel safe using. The borosilicate glass is remarkably sturdy, incredibly easy to clean, and handles boiling water for sterilization without an issue.”
“My baby is exclusively breastfed and refused every plastic bottle until this one. The silicone nipple is incredibly soft and natural—zero nipple confusion! Highly recommend.”
“The anti-colic system actually works. We’ve noticed a huge difference in his fussiness after feeds. It’s a beautiful, premium glass bottle that doesn't leak or flow too fast.”
Made with premium borosilicate glass that withstands extreme temperatures — straight from the freezer to boiling water without cracking. Unlike plastic bottles that absorb odors, stains, and release microplastics over time, RiseCub Pure stays crystal clear after hundreds of sterilizations. The wide neck makes filling and cleaning effortless, and the food-grade liquid silicone nipple mimics the natural feel of breastfeeding for a smooth, stress-free transition.
90ml: Newborns, 0–3 months 160ml: Babies 3 months and up Each bottle comes with a soft, breast-like silicone nipple designed for easy transition between breast and bottle. Choose your size and color at checkout.
