The dynacast splint prelude uses a single-layer patented synthetic substrate to rule out the possibility of delamination that can cause wrinkles. The substrate has no wrinkles or folds. The application time is quite fast. The product is ultra-adaptable with a safe immobilization. It is padded with fabric on both sides. This padding, as it covers possible sharp edges of the substrate, helps to reduce skin irritations. The splint provides quick recovery and guarantees protection and success in the treatment process. The dynacast splint prelude is ultra versatile.
