Reflective Birkenstock cover (or other sandals).
Buy each band separately, so you can mix and match if you want to.
4 bands = 1 pair (if you have Birkenstocks/Sandals similar to the images).
Or maybe you just want one 'feature band' on each shoe...
Slide over your sandal straps to add more visibility to your life.
Also great for covering worn-out sandals to make them look new. :D
Made from hemp/organic cotton.
