With the solid one piece design and complete UV protection, the Twisty Peg will flex and twist as required, but will never break or snap. The no-spring design ensures that the Twisty Peg will not rust, seize up as it becomes used or stain your clothes. Twisty Pegs are washing machine safe, should they become dirty and are child safe. One package includes 20 Twisty Pegs in four different colors.
