This is a set of 10 carabiners. Made of aluminum, they are very light and can be used for various purposes such as keychains. I think they are not suitable for serious mountain climbing. 【Size】 　Length: Approximately 5.5cm 　Width: Approximately 2.5cm 【Product Condition】 The product will be disinfected, wrapped in cushioning material, and shipped. Although it is new and unused, there are minor scratches, so I have marked it as "slightly scratched or dirty."
