Test your cocain - with the RED-E-METER cocaine testing solution!
The RED-E-METER is a very easy to use cocaine testing liquid and allows everybody to test his cocaine.
Take a common translucent water drinking glas and place it upside down. Place now one drop of the Red-E-Meter cocaine testing solution on the bottom and add a knife point of the sample into the drop.
All immediately turning blue is cocaine, all the rest is cut-off.
For ca. 60 tests.
