This is truly an innovation. Repellents throughout history have become a problem for people's health and for the environment. However, little by little we have seen a concern on the part of the different laboratories to improve the processes and to adapt to the needs of the environment, this is a really impressive one. Now it remains to be seen if it creates allergies, if it is harmful to pets and what to do with the bracelet or ring when the effect is over. Thanks for sharing.
