These drinking cups are made of high quality and UV resistant plastic. The yellow float in combinationwith the green drinking cups creates a beautiful whole. The round model has no seams orcracks and is very easy to clean.The risk of leakage is truly limited. These larger drinking cups work with a float:the drinking cup is filled with water and as the yellow float starts to float,the supply is shut off. This way the animals always have clean drinking water.
*These will come with either a yellow or green lid
