If you are cupping yourself at home, it is best to use ceramic cans, which is not easy to be dangerous. It is best not to use glass tubes or bamboo cans to avoid damage, scratches or fire. This is my answer to your question. Thank you. Just use a glass jar that has been cleaned and disinfected. You can mainly look at the cans. Don't break the jar. You should pay attention to the best use of alcohol. Don't pinch with your fingers to prevent your skin from being burned by too much alcohol. Don't bake the jar mouth into the jar. Cupping time should not be too long, only about 5 minutes. You can also use an air pump. Convenient and simple. After pressing on the plump skin, the gas inside can be exhausted to achieve the effect of adsorption. The advantage of this jar is that it is convenient and easy to use, and most of it is made of plastic, so it is not easy to drop.
