UBMOM Signature PPSU Straw Cup [280ml]
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.
