This hoop is inspired by a love for science! This tubing is sun shifting, it’s white indoors and turns blue when exposed to sunlight! It has a unique reflective tape design layered over it, yellow on the outer rim, white on the inner rim, and blue stripes every quarter of the way. This hoop is truly unique and fun! Available in 5/8” and 3/4” polypro tubing. Measured in outer diameter and comes with a push button connection for easy travel. Comes with clear tape protection layer.
