These thick corner guards are easy to install. While I don't know the exact length of the guards themselves, judging by the size of the box, I think I used about one full wrap. There are 7 corner guards. I used these when my child started to stand up, and they saved me many times. They are in good condition, but they were purchased about two years ago and have been stored for a long time. Please consider this if you are not concerned about that. ☺ To reduce shipping costs, I plan to remove them from the box and ship them in simple packaging. - Product Name: Baby Protect - Brand: Coperta - Material: NBR
