When we meet an urgent situation that we need pack up the wound ,band-aid is a good choice.However,if our wound is at the joint,when we do some cleaning such as washing hands or taking a bath,the wound is easily infected because of touching water.’Joint Band-aid’
is designed for this situation and it offers more space to the joint’s bending.It can avoid bursting the band-aid.‘Joint Band-aid’ not only decreases the second injury to the body,but also increasesthe usage rates of objects and avoid unnecessary waste.
