Kids wood hangers are also outgrown so end up in landfill, unless sold and re used, and the metal hook and metal bar with clips will take 50 to 500 years to decompose! Also trees have to be cut down to make wood hangers resulting in fewer trees to absorb damaging CO2. Grohangers use recycled plastic that might have ended up in landfill/our oceans and offer so many more practical features compared to wood hangers. Oh, and just look at the price of wood hangers!!
