The hand-polished plastic handle makes the hairbrush comfortable to hold and use.
The plastic handle shape was developed from the original wooden models, which are still made in small quantities. The plastic handles are hand-finished to remove any sharp edges to feel comfortable in the hand.
Care of the handle:
For plastic handles to maintain their shape, do not boil in water or apply heat to them. Strong chemicals, notably nail varnish remover, can attack the surface or cause the plastic to sink. In addition, these can draw out the coloured dyes and pigments from the plastic. For the wooden handles, all the foregoing applies. Also, the presence of water inside the hairbrush will cause the wood to swell and the coating to crack.
