Understated Hardware, Elevated Finish

The soft dome head and muted galvanized sheen bring a quiet sophistication to exposed hardware moments. I love the square-neck detail—it nests into wood for a tailored, seamless look. Use these to secure bench slats or deck accents where the hardware becomes part of the design story. A dependable, polished touch for luxe, lived-in spaces.

Works well
Size: 3.5 Ounce (Pack of 6)
I just wanted to update my review as I have had more time to review the product. The presentation is well done and in a nice looking box. Initially it did not smell the best in the box but when it gets wet it has a mild smell that is pleasant. It has a great lather, the exfoliating beads feel good, and it does work well. Great product but the smell is mild.

Masculine Scent
Size: 3.5 Ounce (Pack of 6)
Purchased to try something new. Very good product, smells nice and cleans well. However the scent did not last as long as hoped during the day. On the other hand, if you use it just before a date, it will be just right.

Really wanted to like this soap
Size: 3.5 Ounce (Pack of 6)
I waited until I went through 5 of the 6 bars of soap in this pack. It was very well put together with each bar individually wrapped with a cellophane and a nice paper wrapper. The scent upon opening the box was pleasant. Sniffing each wrapped bar to get an idea of how they smelled left me a little skeptical. So here’s the pros and cons: PROS Small bars but they last a long time. 4 of the 6 are scrubbing bars, meaning they have exfoliating bits of walnut shells in them, which for me, blue collar worker, I really liked. Packaging is nice. CONS THEY ALL SMELL THE SAME! I don’t know why this is, but I can only attribute it to the packaging and them being so close together. Pretty disappointing. The walnut bits accumulate in the bottom of the tub and need to be rinsed down the drain. All in all, decent soap without any noticeable differences in smell. Good enough for one purchase, but I’ll be buying a different brand next time.
