JoeFrex - 58 mm Tamper Base KNOCK-CONVEX

All KNOCK CONVEX bottom parts have a slightly convex pressing surface to press the coffee grounds.

Why the name Knock?

After pressing the coffee grounds for the first time, lightly tap (from English Knock) on the side of the filter holder to dislodge any remaining grounds. This allows for subsequent pressing. To avoid using the base of the tamper or the wooden handle for this light tap on the filter holder, risking damage to both the tamper and the filter holder arm, you can now tap with the silicone ring integrated into the base.

Why the name CONVEX?

Normally, the surface of the coffee grounds pressed into the filter holder doesn't play a significant role; whether it's flat or concave, there's enough space between the coffee surface and the dispensing group so that the water can be evenly distributed over the coffee grounds and pass through them evenly. However, if a flat filter is used in the arm, or if much more than 7g (for a one-cup filter) or 14g (for a two-cup filter) is used, the space between the coffee grounds and the dispensing group may be too small for optimal water distribution. For this purpose, you can use the Convex Tamper Base, as it leaves a cavity in the middle of the pressed coffee for better water distribution.

Silky soft pillow cases save hair from tangles
Pillows feel great and keep your head cool plus your hair doesnt get all tangled at night. I have juwt put them out on my bed and havent had a chance to wash them but they seem like theyre made from quality material that should hold up in the wash.

Super Soft
Size: Queen (2 Count), Color: Gray
So I’ve been trying these pillowcases out for a while. Let me tell you if you’re looking for a silky soft comfortable surface to lay your head on look no further. These silky, soft satin pillowcases fill that niche like nobody else. The material is very soft it looks very shiny and feels amazing next to my skin, which is all I look for. The quality is excellent. I’ve really enjoyed these pillowcases and the silver is wearing on me now I need to order some matching silver silky sheets, and I’ll be set. What an amazing value.

4 BUCKS PER PILLOWCASE. DEAL!
Size: Queen (2 Count), Color: Gray
SUPA MODERN Satin Pillowcase, Similar to Silk Pillow Cases Queen Size Set of 2. These silver pillowcases shine like metal, but they are worth 4 bucks a piece. My sister and I each tried one out. She loves how kindly the pillowcase treats her hair and her extensions; no snags, knottting, or rat nests. I love the way the material feels on my face; soothing and smooth. Definitely a good, affordable price for pillowcases, even shiny silver ones.

retty color, but the comfort isn’t there.
Size: Queen (2 Count), Color: Gray
I only received one pillowcase in my package, which was disappointing since it’s sold as a set of two. I’m also not a fan of this satin material — it runs hot and I end up sticking to it. The color is a pretty metallic silver, but the pillowcase itself feels cheap compared to brands like Kitsch. Overall, this one just isn’t for me.
