Flexi Vario Tape Blue Large. Dogs love to explore when they are out for walks and if you are not careful enough they might just take you along with them to explore a new patch of grass ora flower. It is in those conditions that a retractable leash really helps. The Flexi Vario tape has been made with utmost care to provide great ergonomic support to pet parents and good support for the pooches too. The band has a soft grip and does not cause discomfort.
