Transform your existing bottles into a toddler trainer cup in seconds. (Note: Bottles are NOT included). 360° DRINKING WITH WEIGHTED STRAW – Designed for active babies. The innovative gravity ball straw moves with the liquid, allowing your little one to drink smoothly at any angle—sitting, reclining, or lying down. Perfect for transitioning from nipple to straw while preventing air intake.

The non-slip, easy-grip handles help baby hold the bottle firmly, building confidence and motor skills. The set is easy to assemble and disassemble for thorough cleaning (2 cleaning brushes included).
