The Patented FunLPro Caps are sold separately in packs of 10 and 20 to add on to every day fluid containers that require pouring. Many packaged fluid products today can be costly and dangerous if spilled, and some are even deadly. FunLPro Caps twist on to most fluid containers providing a sterile, extendible, no-spill directional pouring spout that will protect you from unwanted spills and your family from dangerous chemicals. Built directly in to the cap itself, you’ll instantly have a funnel that makes the most difficult pouring situations a breeze. Throw a pack in your glove compartment, on your boat, in your tractor, or in your travel bag and just Pop, Pull, and Pour. Strong enough to reuse! Affordable enough to throw away! You decide.
