This pack of 20 Bamboo Clothes Pegs are made of sustainable bamboo and a steel spring. They come in a recycled and recyclable cardboard box meaning they are 100% plastic free! Whoop! The bamboo pegs are completely biodegradable and the steel spring can be put in recycling. Bamboo is super sustainable. Needing no sustainable product. It needs no pesticides or fertiliser to grow. It’s a super fast growing grass that is more efficient at taking CO2 from the air and producing more O2 than trees. WHY I LOVE THIS Bamboo clothes pegs are a great alternative to plastic pegs and are incredibly strong and long-lasting. Bamboo pegs will not stain your clothes like other types of wood does due to having low tannin.
