It has a slightly matte, solid brass gold luster. Because it is not coated, but uses solid brass, it will change to an antique color over time, giving it a vintage feel, and you can enjoy the aging process. 【Rust-Resistant and Highly Durable】 Brass has the weightiness unique to metal, but it is also a material that fits comfortably in the hand. It not only creates a sense of luxury, but also excels in durability. Brass is resistant to water and humidity, and has the characteristic of being rust-resistant, so it is less likely to deteriorate even after long-term use. Compared to iron or aluminum carabiners, it is more resistant to corrosion, and can be used with peace of mind in outdoor activities and everyday use. Solid brass is hard and sturdy, so it is resistant to drops and impacts, and has the advantage of being less likely to break even after years of use. 【With Screw Lock Function】 Equipped with a screw lock function, it can be securely fixed with a screw-in mechanism, significantly reducing the risk of accidental opening compared to regular carabiners. General spring-type carabiners can open with strong impact or friction, but with the screw lock type, there is no need to worry about accidental opening, improving safety. 【Product Details】 ■ Material Brass ■ Color Antique Gold ■ Type 〇 Pear-shaped ■ Dimensions (approx.)
