Calf Bottle with Screw-On Nipple

EXTREAMLY POOR QUALITY. THE BOTTLES COLAPSE AND SO DO THE NIPPLES. THE E Z NURSE ARE SOOO MUCH BETTER

I've used the screw on bottles for a while now, and they do leak if you cross-thread them. But there is an easy solution to this: Only tighten them barely enough to keep the lids on. They do not need to be super tight and they won't leak if the nipple is

I order 2 of these bottles to start razing orphans and they leak very badly around the neck where the nipple screws on and the ring cross treads and does not and will not get tight. They leak very badly. Jeffers sent me 2 more and they do they same thing.
