First I would like to thank Climax Metals for their professional customer service. It was an international shipment to Southeast Asia. Not only did the product arrive safe and sound, I received my order ten days earlier than expected! Thank you again Climax Metals for your service. Others could learn from you. However, the collar is very well made and is a great example of adapting modern technology to holistic treatments. It will likely take some practice to put the collar on to avoid pinching or damaging the skin. But with a little patience and making sure you get the right size, you should be fine. One last point, you'll need a Torx T30 screwdriver to fasten the screws. Good luck and stay healthy!
