The sign necklace contains EM beads. Effective micro-organisms are baked into the beads. The effectiveness of EM beads is based on the principle that energy can be retained and transferred by binding these properties in baked clay. The beads therefore emit a vibration that we and the dog do not feel, but where the ticks, fleas and lice don't like it.
You "activate" the beads by wetting the beads under the tap and letting them dry in the sun (UV light). You must repeat this every two to three weeks to rinse off the dirt and reactivate the beads.
The band must be worn 24 hours a day and will lose its effect after about 3 to 4 weeks. This operating time depends on the maintenance of your collar. Dirty beads obviously don't work.
