Keep your child safe with magnetic child locks. - Set Contents: Set of 4 / Set of 8 - Function: Magnetic child lock - Usage: Safety measures to protect your child from household dangers Thank you for viewing. This is a door stopper to prevent children's mischief. I bought it for my new home, but I bought too many, so I'm selling the extras. It was easy to install, and since the stopper isn't visible from the outside, I was able to keep things tidy while ensuring safety! There are 4 sets of brand new items that haven't been taken out of the bag x 2 There is 1 set of 4 that has been taken out of the bag but is unused. I'll include one extra as a bonus. There are 13 in total! The outer box has English writing, but there is a Japanese instruction manual inside. If you have any requests for a price reduction, I'll consider it, so please comment!
