I bought these at a home center, but they don't fit my door, so I'm selling them. One is opened, and the other is unopened. The opened one was only used for testing and not used regularly. Because of the steep slope, I think they would fit well on doors with a wider space underneath. Please check the size before purchasing. No pets live in the house. Purchase price: about 850 yen/piece - Material: 100% natural rubber - Features: With magnet - Color: Black - Shape: Triangle - Size: 120x20xH45mm
