In ready-for-use protective packs for air- and/or moisture- sensitive colour-indicators on a carrier, the carrier (2) and the indicator are enclosed, air- and water-tightly, in an at least partly transparent protective envelope (1) of air- and water-impermeable material. This protective envelope comprises at least 1 puncture (3) in an area coming into contact with the testing liq. The puncture is sealed, air- and water-tightly, with a cover-layer. |
