These 4" Red Bamboo Knot Picks are made from all-natural bamboo and are eco-friendly for maximum convenience. They feature a knot top with a skewered end and are ideal for use with sliders, sandwiches, fruit, and appetizers. They are more durable than traditional plastic picks and are sure to impress. Bamboo products are made from the part of the plant called the sheath. The sheath is the protective outer layer of the bamboo's culm that grows in young plants. When the plant has matured, the sheath falls off and is collected, cleaned, and boiled. Once the sheath has been laminated it is then pressed and bonded into the desired shape. This process is completely eco-friendly and does not involve the use of chemicals or toxins. Featuring a sleek design, these picks are a wonderful eco-friendly option.
