Ferm Living Hook Natural wood Wood. Dimensions: 7 x 5.2 x D 3.8 cm. These Cairn hooks, with their soft curves and carved details, will add an artistic touch to walls. Our Cairn collection, made up of a number of organically shaped pieces, is inspired by Cairns, piles of stones often erected for commemorative purposes. The delicate, rounded edges give the hooks a unique look. The Cairn hooks have been carved from solid, FSC-certified ash and treated with a carbonised finish that gives the wooden its dark brown, rustic look. Set of 2 hooks. PLEASE NOTE. The hooks are polished to give them their organic shape so slight variations in size and colour may occur. The charred scent of the wooden will diminish over time.
