This tubing is brand new to Hoopologie, please check it out if you've been wanting something different than what's available in the market today. This tubing is a great tool for beginner/intermediate hoopers looking to refine their skills with a brand new feel. This tubing is 7/8th OD and 3/4" ID. It accepts 3/4" inserts. This tubing is bouncy and has spring like all polypro, but it's great to feel the slightly added weight of a larger hoop for learning skills such as body rolls, breaks & paddles. This size is extremely fun and gives an entirely different perspective to your hoop experience. You can make really nice small, medium and LARGE hoops out of this that are not floppy.
