This is the "Standard (Cross Cut)" type nipple replacement for Dr. Betta's baby bottle.
The cross-cut type can be used for fruit juice. Other round holes can be used for babies that are a little unsatisfied.
It uses silicone rubber, making it durable and resistant to deformation and odor.
Replacement parts with round holes are also available.
