Avanos MIC-KEY Continuous Feed Extension 30cm (12 in.) . Condition is New. Shipped with USPS. This feeding tube can also be used for bolus feeding with gravity I find its a lot more gentle to use due to the 90° angle on the feeding tube. Versus a straight shot to the tummy this has a 90° angle to help slow the formula into the tummy making it easier on your baby tummy.
