Industrial Poise in a Sleek Metallic Bolt

This hex cap screw delivers a crisp, architectural note—clean facets and a cool zinc sheen that feels considered, not utilitarian. I love the confident proportion of the hex head; it punctuates wood and metal with sculptural precision. Style a row of exposed fasteners on a custom shelving bracket for a tailored, atelier vibe. It’s a small detail that elevates the whole project to quiet luxury.

Body pillow covers
Color: White, Size: Body(20"X 54")
I ordered the body pillow covers. They fit my pillow perfectly and the fabric is smooth and silky, but I did not find them cooling.

Cooling King-Size Pillows (used on a Queen pillows to tuck the extra in)
Color: Navy Blue, Size: 2 Pack King(20"X 36"), Color: Navy Blue, Size: 2 Pack King(20"X 36")
🛏️ Product Review: Cooling King-Size Pillows (used on a Queen bed) ⭐ The Good • These are king-size pillows, which I actually love on a queen bed because I can tuck the ends into the fabric. • The fabric feels slick and cool, but you don’t slip off of it. • They feel cold to the touch right out of the package (which is wild). • I sleep extremely hot and even run fevers at night due to a medical condition (literally 101–102° sometimes), and these pillows still stay cool where I lay my head. • I’ve honestly never slept this well in my life. • For the price, you cannot beat them, and they go on sale often. • These beat any high-end version I’ve tried. • If you sleep normal-temp and not lava-hot like me, you’re going to be VERY comfortable with these. ⚠️ The Bad • The fabric does show crease lines. • If wrinkles bother you, this might annoy you (doesn’t bother me personally). 🔧 What I’d Change / Tips for Care • Don’t use fabric softener — it clogs the cooling fabric and ruins how it works. • Wash with unscented detergent + a little vinegar. • Dry on low heat only (do NOT dry on high if you want the fabric to keep working long-term). ✅ Final Thoughts I will literally never not own these again. If you sleep hot, night-sweat, or just want a pillow that actually stays cool — these are it. 10/10 recommend.

Love it but it stains
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
I love these but had to knock some stars down for a single reason. They are soft, the material is somehow both substantial and airy at the same time, and a smooth, silky (not satin), cozy texture. The color was exactly as pictured. The envelope style works great to keep my pillows covered. The fabric lays perfectly. I love sleeping on this pillow case. Took two stars off because every single atom of oil on my face stained it immediately and won't come out in the wash. Its not subtle. You can see anywhere my face has been, forever. I don't have some incredibly oily face or hair, I've never had this happen to another pillow case in my life.

Silky and Soothing
Color: Cream, Size: 2 Pack Queen(20"X 30")
I thought I was getting 1 of the queen sized but I got 2. I got these for my Pomeranian's fuzzy pillow. He's always hot and these are very cooling and very good quality. He loves them and are very comfortable for him. They totally transformed his shaggy old pillow. I used the larger body pillow covers to replace the covers I had. They matched my bedspread perfectly. I use 2 body pillows along the exterior wall in my bedroom where there is cold coming through the floor in the winter. I'm sure I will enjoy them in the summer when it's hot too!
