Pre-printed, red and black on a white background, THC content warning labels. These permanent labels are made of a durable thermoplastic film, and resist abrasion, scratching, as well as spraying and wiping with alcohols, detergents, and surface sanitizing wipes. Ideal for labeling a wide range of cannabis products (THC concentration of 10 micrograms/gram and higher) packaging containers, such as plastic bags, bottles, and cardboard boxes. These standardized cannabis symbol labels are also UV resistant, and tearproof, able to withstand a wide range of temperatures ( -40ºC to +93ºC / -40ºF to +200ºF), perfect for use in any environment, and storage conditions.
