Iron-on labels for clothing are permanent and cannot be removed from the garment once applied, but it is possible to place one label on top of another once ironed.
Garment Labels are non-permanent and are intended to temporarily mark garments so they can be carefully removed. Once removed, the label will no longer stick to the first time.
Adhesive Labels for objects are dishwasher and fridge/refrigerator resistant but can also be removed if necessary.
