The team produced over 30 sketches to come up with a design that fulfilled all requirements
When the rubber tip was being developed for the original Soft-Picks, selecting the right materials was essential. The soft exterior made the brush more comfortable and less aggressive than wired brushes, while the core had to be hard enough to be inserted between the teeth without bending or breaking.
The team searched for the perfect combination. “We have a big stock of materials we can test here, and we tested many different combinations of materials to find the exact hard-soft combination”. The selection process is a cycle of trial and error.
After extensive tests, they found what they were looking for: a firm but soft rubber for the bristles, and for the core, a material with the necessary stiffness and enough flexibility to ensure perfect performance of the product.
