JoeFrex - 57 mm Tamper Base KNOCK-CONVEX

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

Why the name Knock?

After pressing the coffee grounds for the first time, lightly tapping on the side of the filter holder to dislodge any remaining grounds. Subsequently, 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 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, the Convex Tamper Base can be used, as it leaves a cavity in the middle of the pressed coffee, for better water distribution.

Buy small and not big
The product was definitely an awesome product I wore the pants one time realize that I got a Size 52 I should have got a size 50 they are a little too big on me. I probably pass them on to a friend that's a little bit bigger than me and I need to lose 100 lb so and then all my other jeans will fit me but I will not have a problem buying any type of jeans from this company. I really enjoyed the product and I know I'll be buying smaller sizes in the future

retruns not free despite being labelled as such.
waist fine. length...rediculously long, thigh and calf stupidly narrow for larger sizes. also, despit it claiming that it offers free returns, they evidently charge something like $4? i dont know yet as they dont say exactly how much, but rather that it will be deducted from the refund. very deceptive.
