These 3 Packs of TRAVELJOHN JR disposable urinals are designed for boys and girls 2 years old an up. They are convenient, unisexed, sanitary, personal urinals containing "Liqsorb", the key ingredient that makes this work. Liqsorb is a combination of an exclusive biodegradable non-woven fabric pouch containing a biodegradable polymer substance that immobilizes bacterial growth quickly - absorbing liquid waste and turning it into an odorless, spill-proof solid gel bag that is non-toxic and waste disposal safe. The unisex adapter makes it easy for anyone and everyone, even children, to use while sitting (providing there is the use of gravity with an unobstructed, free-flowing opening) or standing, and a spill guard prevents back flow during use. The TRAVELJOHN JR urinal will hold up to 20 ounces (600cc), provides a volume indicator, is leakproof, hygenic, compact and easy to use. NO CLEAN UP, just use and throw away without the worry of spilling or contamination. THESE ARE GREAT FOR POTTY TRAINING or when children "gotta go" Dimensions: Folded: 2"x2"x5", Unfolded: 5"x11", Weight: 1.5 oz unused. Useful tip: During use, hold the gel bag toward the bottom of the urinal avoiding the chance of it floating up to the lip of the opening to assure a spill-proof experience.
