SpinOlution bobbins are made from Baltic birch and are shatterproof. Each one is glued by hand and tested for durability and function by SpinOlution's quality control department.
Any bobbins that break within 1 year of purchase SpinOlution will replace for free. If your bobbin breaks, email a picture to email@example.com with your shipping address and proof of purchase to receive a free replacement.
NEW: Golden Whorl SpinOlution Models have larger flyer rod sizes to stabilize the flyer when spinning at high speeds. Please reference your flyer rod size when reordering more bobbins. Note: 3/8" bobbins have a black bushing in the front of the bobbin. 1/4" rods have a white bushing in the front of the bobbin.
