A Clean, Classic Fastener for Crafted Woodwork

The domed silhouette and zinc sheen bring a refined, utilitarian elegance to cabinetry, benches, and custom storage. I love the square-neck detail—it bites into wood for a smooth, unbroken face that feels tailored. Pair with pale oak and matte black brackets for a modern workshop aesthetic. Essential hardware that quietly elevates everyday builds to luxe, thoughtful design.

Nice sweater
I wasn't sure what to think of this sweater. It looked nice, but I don't know. Then I wore it out one night. I totally got laid that night. Highly recommend.

GREAT SWEATER...BUT...
Size: X-Large, Color: Khaki
I really like this sweater and am a big fan of this brand. The material is good quality for what you're paying and the material is soft and comfortable and provides good warmth for those chilly mornings or evenings. So why four instead of five stars? Quite simply, the fit. Although it's a classic style and looks good out of the box, I thought the fit could have been better. I ordered the right size and it actually fits my body well enough, but the overall presentation seems a tad off, especially around the chest and upper arm areas. That being said, it's definitely not a deal breaker by any means and I fully intend to get plenty of use from the four colors I purchased. Just don't be terribly surprised if it doesn't hang on the body qauite exactly as you might have intended. Of course, that's a pretty subjective point of view and yours may be totally different.
