I've been a HUGE FAN of these wonderfully sublime, colour-changing balls of yarny delight ever since I learned to crochet, and am now stocking a selection here at Yw Towers*.
They are 75% Strong quality, virgin superwash wool & 25% biodegrable Nylon .. perfect for your next pair of Stripy socks or a lightweight Spring scarf.
I'll even send you my Zauberball Scarf pattern FREE with your purchase - One Zauberball and a 5mm crochet hook makes a scarf approx. 150 - 170cms long!
