How many labels are on each roll?

Each label is 4x6 inches (100x150mm). The roll core is 1 inch (25mm), which fits most desktop thermal label printers.

Are they water-resistant or long lasting?
These labels are designed for short-term shipping use. Direct thermal paper is not waterproof and the print can fade with moisture, heat, friction or strong sunlight. For wet conditions, we recommend protecting the label with a clear pouch or over-label.

Store in a cool, dry place away from heat and direct sunlight. Keep rolls in the bag or box until use to avoid dust and handling marks on the label edges.
