This side release plastic clip is ideal for projects that will come in close contact with skin because it is contoured for your comfort. Sturdy, consistent, and comfortable, they are easy to open and close; a smooth release when pressure is applied helps to avoid accidental release. This YKK curved buckle provides you with the versatility to use with many different applications. Some projects could include: cosplay, costumes, backpacks, purses, collars, bracelets, watches, belts, and many other ventures! Sturdy, contoured plastic allows you to move and perform your daily functions with ease. These are also great additions to small pet collars. When creating a collar for pets, contoured accessories are more comfortable to wear; also allowing for a tighter fit so that your furbaby can feel more snug. Created to be used with webbing that is a 1 inch width, this clip works great with paracord, nylon, polyester, polypropylene, and is compatible with many other fabrics. D-rings, buckle, triglides etc. are matched by the size of the webbing or straps they are meant to be used with. These are made for use with 1 inch webbing or straps. Dependable and strong, these are essential for your craft needs. These clips cinch or hold webbing well when using them with heavy or super heavy webbing. However, if you are using lightweight webbing, we highly recommend using a triglide slide along with this buckle.
