Mostly made from old jeans, stretchy ones work best. Sometimes I sew them so they are all the same colour (denim), and sometimes so some of the fabric is inside out (multi denim). They vary a lot in colour and have faded areas of cloth. 95 g in weight they are larger than UV Rollunds, squidgy to feel, they don’t roll out of the hand on impact.
These are handmade so allow time for larger orders to be made, also allow for busy times of year.
