Floor shops in the decoration market generally sell it, which is a decorative buckle made of resin. You should choose a button called right angle for your round edge. There are many colors to choose from. This button can be heated into the shape you want with a general household hair dryer, but it needs to be blown into the shape you need slowly. The operation method is as follows: first, fix one end in a circle (it is best to hold it with one hand to avoid damaging the appearance); Press the card buckle on the arc edge of the wardrobe fillet according to the circle, and blow it with a hair dryer, which should not be too close to avoid the surface sticker peeling off; Follow the above steps step by step, and you can blow the buckle into the shape you want, and ensure that it is beautiful and practical. It is best to use glass glue to fix it, so as to ensure that the expansion and contraction of the floor will not cause the buckle to tilt. The price of this buckle is generally 20 yuan/branch/2.7m.. If you can't find it in the local market, you can also find it on Taobao. This kind of buckle is called "resin buckle" or "Mohs buckle", which is made of recyclable plastic, also called polymer foam.
