UBMOM straw cup includes Backflow Prevention Disk to prevent the liquid in the bottle being backflow by pressure / temperature difference (hot/cold drink), while the Smart Cap is easy opening and at the same time can also help preventing water leakage for moving. Also, UBMOM straw cup can be used as a feeding bottle by replacing the straw nipple with the bottle nipple.
good my little one loves them
My daughter enjoyed using this bottle and drinking more than other products. So I purchased another two.
This is my second time buying these cups, I've replaced all other cups to these. Very good, we loved it!
My baby loves the bottle a lot. good texture, nice colour.
