OPTIM Interdental brushes by Stoddard are precision made in the UK. They are manufactured using only the highest specification materials. High tensile strength, plastic coated, stainless steel wire at the core prevents them from buckling. For longer life the filaments are made from the same memory retentive nylon as used for toothbrushes. The brush is locked to the handle using a revolutionary production process making it virtually impossible for them to separate.  They are available  in the same colour coded sizes that practices are already familiar with.
