Two of them were used for about a year and a half, and the other two are unused. I used them to prevent network equipment from falling, but I no longer need them because I changed the equipment, so I am selling them. They have a unique size and are well-made, and I found them very useful and convenient. I will include two sets of unused earthquake-resistant seals.
