JoeFrex - 55 mm Tamper Base KNOCK-CONVEX

All the lower parts of KNOCK CONVEX have a slightly convex pressing surface to compress the coffee powder.

Why the name Knock?

After pressing the coffee powder for the first time, lightly tap on the side of the filter holder to dislodge any remaining powder on the sides. Then it can be pressed again. 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 integrated silicone ring in the base.

Why the name CONVEX?

Normally, the surface of the coffee powder 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 dispensed from it can be evenly distributed over the coffee powder and pass through it uniformly. However, if a flat filter is used in the arm, or if much more than 7g (for a single cup filter) or 14g (for a double cup filter) is used, the space between the coffee powder and the dispensing group may be too reduced for optimal water distribution. For this purpose, you can use the Tamper Base Convex, as it leaves a cavity in the middle of the pressed powder, for better water distribution.

MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!

Squeaky ball

Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.

Really indestructible
Color: Yellow
As advertised. I have an obsessed 16lb mixed breed dog that has destroyed everything purchased that says indestructible. Until now... These balls really are indestructible. She loves them and plays with 2-3 at a time. Chews on them and still going. They are the size of regular tennis balls. Others are slightly smaller. These are great and bright... Mooky highly recommends.
