These wrist warmers are a marvel as they can be worn in so many ways. They can act as a long, single layer wrist warmer or a cosy, shorter double layered version and there are colour options too as each end is different. Every pair is unique; the colours you see in the second photo along give an indication of the variety of colours used. If you have a preference, a light or dark shade for example, please pop a note in the Order Notes section at the bottom of the basket page and we'll do our best. If you have a particularly broad or narrow wrist it would be helpful if you could let us know; the wrist warmers are one-size but we will always try to get the right fit if you have special requirements. The wrist warmers measure approximately 28cm long and have a circumference of approximately 16cm. They are machine-washable on a cold setting.
