This amazing product is called an EM bead which is all natural and works with the human tissue to repel ticks. These need to fit snug (not tight) so there is skin contact.

The EM® Ceramics are a special type of clay pipe containing effective microorganisms
(brand name referring to a family of microbial-based products), and fired at a very high
temperature. The Ceramics emit far infrared rays which are highly compatible with human
and animal tissue. The rays penetrate the tissue, activating cells, increasing circulation,
breaking up cell clusters, improving overall body function … all the while creating an
environment that ticks and fleas cannot thrive in. There are no contraindications at this
time – no negatives! In simple terms, the rays create an environment that ticks and fleas
will avoid. The beads do expire or wear out over time. Each metabolism is different, and
the beads will work longer for some than others. Get to know your geographic area and
time the bead activation accordingly. If you have ticks in your area in early spring,
products should be put on earlier in the year. If ticks are more prevalent in the fall in
your area, perhaps mid-summer is better timing to begin. If the ticks are active
nearly all year with the exception of the coldest months (late December to February), we suggest moving to annual use … 1 product started in February, and then a new one in July.

NOTE: Do not use soap on the beads, do not put them in salt water or pool water. Charge the beads 6-8 times a year by washing the collar with warm water and an old toothbrush then put it in the sun to dry. The sun will recharge the beads.
