Using these Dymo XTL labels is easy. First, choose the right label for your surface. Then, use a compatible thermal transfer printer to print your text or design on the label. When applying the label, make sure the surface is clean and dry for better adhesion. For best results, avoid using the labels in extremely high - humidity areas if possible. To maintain the labels, keep them away from direct sunlight and chemicals. If you notice any dust on the labels, gently wipe them with a dry cloth.
