Foal Navel Dip Pots can be used to hold navel disinfectant/iodine. They have two chambers & squeezing on the lower chamber causes the liquid to flow into the top chamber, ready to dip the foal's navel in.
The non-return valve stops liquid from flowing back into the lower chamber, thus keeping the contents of the lower chamber clean.
Please note, navel disinfectant/iodine is not included.
