These are wooden sticks used by FoBIRD in videos. These sticks are made entirely from nature so they are safe for health and the environment.
The white of wooden sticks is the original color of bamboo ordered in Vietnam. To make brown, these bamboos are boiled at high temperatures, which are then dried and meticulously processed by FoBIRD. From that, create wooden sticks with high uniformity, good flexibility, and it is difficult to find another natural material like that in the world.
