When it is time for potty training, boys need something different. LiL Marc looks like the full size urinals found in public restrooms, only on a smaller scale. LiL Marc is just the right height for your little boy to learn to stand up and aim. This means less mess for you and more success for your little boy. The difference between this listing and the other LiL Marc Urinal listing is if you want two LiL Marc Training Urinals we can ship them in one larger box and pass the saving on shipment to you.
