EM ceramic is said to have a positive effect on the immune system and to be effective against ticks and parasites. Unfortunately, this effect has not been proven. The paracord bracelet with EM ceramic beads is available in these sizes: — 20-30 cm neck circumference — 30-40 cm neck circumference — 40-50 cm neck circumference — 50-60 cm neck circumference Pattern: Zomb Closure: sliding lock A leash must not be attached to decorative bands! For the EM ceramic beads to be fully effective, they should be worn for 24 hours. Once a week, you should wet them, dry them in the sun and thus “recharge” them. This product is handmade. There may be slight variations in shape and color.
