Please be aware that necklace lengths are measured without the pendant. All necklaces are made with brass plated findings which are lead and nickel free. The brass may darken over time, brighten by rubbing lemon on the chain and rinsing with water. The wood pendant may be cleaned with a damp cloth. The poplar wood used for the pendants is very light and durable, all pendants have been sealed for water resistance. All materials used are non-toxic.
