The design of the XM interdental brush follows on the product bestseller, the classic Spokar X toothbrush. It thus expands the product line and contributes to its attractiveness with its design. Based on many studies, good dental care is absolutely essential for oral hygiene. Interdental brushes are still a much underestimated tool in this area, so our goal was to create an attractive and accessible design. The shape of the letter X is the result of the natural position of a thumb and a forefinger pressed against each other on a piece of clay. The short X-shaped handle offers a stable and ergonomic grip. Spokar XM is available in several color-coded sizes.
