Firmly and securely tighten. It will not loosen even if it is a little tight. I used a cheaper (harder and thicker) type than before, but when I pulled a little tightly I could not use it unwind unwound. I am very satisfied with this item.
It was different from the color at the time of previous purchase. It was pretty light blue, so when I arrived it was pretty puzzled. It was very shocking. Is it the same as the item you purchased last time? The outer box of the item was considerably damaged, and it became a sad shopping.
