Set of 4 door stoppers. I purchased these on Amazon about six months ago and used them for about a month as a makeshift lock for my room. I only used two of the four; the other two are unopened. I measured the size, and they are 9cm long x 3.9cm wide x 1.4cm high (please understand that these are amateur measurements, so there may be some slight error). There are no noticeable stains, but these are used items, so please refrain from purchasing if you are concerned about minor details.
