I realized that people like my husband aren't going to rock a patterned fabric bag on their tool belt, and wanted to provide a compact option for travel as well as personal preference.  This container stands 3.75" or 6.98cm tall and has a ring to attach for carrying with your keys.  The straw is made of stainless steel, and screws together to create an adjustable option ranging from 5.75" (14.6cm) to 8.625" (21.9cm).  The kit includes: 1 straw, 1 brush, 1 cleaning cloth, 1 container.  Dishwasher safe.
