Acetal handle has a tiny ding at the top, its hardly noticable.
Acetal is a resilient, high-impact material that is resistant to fracturing. Having a whole handle made from this material makes it particularly well suited to those who may like to knock the portafilter (not advised at any time.)
Being warm to the touch and much lighter than aluminium, Acetal provides a tamper with the balance and tactile benefits of hardwood (warm to the touch and bottom-heavy) but with the strength and durability of aluminium.
As with the aluminium handled tamper, it can be washed or wiped as required; custom engraving shows up gloss black against the matte black surface finish.
