The bamboo skewer raw material is bamboo,it's disposable.  if you want to put it into the oven, it's best to soak them in water.in this way, it avoid your skewers from burning to a crisp, because the bamboo skewer is dry, so we recommend soak it into water more than 30 minutes,  this will do a decent job at keeping your skewers intact during the cooking process.
