***GREAT STOCKING STUFFER*** Most reusable straws are difficult to clean. Either you need a separate cleaning brush, or you have to pry the straw apart, only to find that mold has built up in all the nooks and crannies. UnStraw is humangear’s answer, in the form of a straw that opens easily for cleaning and features a mold-resistant design. UnStraw’s key innovation is the signature two-piece hinge mechanism that enables the straw to split apart quickly and re-seal automatically. 4-packs are available in 2 color options. Perfect for your stocking stuffers this holiday season or your favorite eco-conscious friend!
