To use the EG25 Micro Smoke, simply pull the wire as it uses the Wire Pull® ignition type. Wait for about 2 seconds for the fuse to work, then the unit will start emitting smoke from the top for around 30 seconds. Keep in mind that the smoke color will be the same as the font color on the product. Store these units in a cool, dry place. Don't expose them to extreme heat or moisture.
