As one of your babe's first forays into drinking solo, it is so important that sippy cup lids are soft and safe for developing gums and mouths - no hard edges here. When you remove the sippy top, you return back to EKOBO's signature FSC-certified fibre cup. From weaning and beyond, use and reuse this cup with your growing kiddo, but we've found that it is also quite perfect for a little coffee :)
