For leather crafters looking to step up their stitching game, this Bafnsiji spacing tool set is one of those simple but essential tools that makes a huge difference in your finished projects. The set comes with the main tool handle plus four interchangeable wheels in different sizes - 3mm, 3.5mm, 4mm, and 5mm - giving you flexibility for various stitch spacing needs. The alloy steel construction feels substantial and durable, while the wood handle provides a comfortable, ergonomic grip that's easy to control during use. The wheels rotate smoothly, creating consistent, evenly spaced markings for your stitch holes. What's really clever is the curvature design that helps you work around leather corners and curves without compromising spacing consistency. The stable structure means you get straight, parallel lines every time, which is crucial for professional-looking stitching. It's perfect for marking stitch holes on wallets, bags, belts, holsters, or any leather goods where consistent spacing matters. The included wrench makes changing between the different wheel sizes quick and easy. Whether you're a beginner learning leather craft or an experienced maker looking for reliable tools, this spacer set delivers precise results without breaking the bank. The multiple wheel sizes mean you can match the spacing to your project's scale and aesthetic - finer spacing for delicate items, wider for more rugged pieces. It's one of those tools that seems simple but actually significantly improves the quality and professionalism of your leather work. The build quality feels like it will last through years of projects, and having four different spacing options in one set means you're prepared for whatever leather work comes your way.
