It’s definitely cool. One issue could be that the top half is made of a plastic which is more susceptible to staining. The bottom, white section, of the shaker now is made of Tritan which we’ve used in part for it’s anti-staining properties (it’s not impossible to stain, but much harder). The top is made of polypropelene which has a much more open structure and means it stains easily (this is why the old buchsteiners went orange in the dishwasher). So a white top half could make that a problem.
Not out of the question though and we are experimenting with colourways for the shaker as you can see from the 5000 club.
