Pet ID TUUBs are available in two sizes and six beautiful bright colors. 
They are composed of anodized aluminum alloys and are corrosion and water resistant. We cannot however, guarantee the color finish, which depends on the condition of which the Tuub is being used. The large TUUB measures 1- 3/16 inch in length by 0.6 inch in diameter and comes with a split ring for attahing to a collar. 
Each TUUB constains a paper slip for ID descripiton and contact information.  Additional information can be added by writing on any paper strip of the same width, and insert into the TUUB.
