Designed to stop light cured bonds from setting in the dappen dish. Deep, narrow well design restricts the light from penetrating, thus preventing the cure of the bond, while reducing evaporation. A single drop of bond can last for up to 24 hours. Prevents waste and saves you money. Standard applicator brush can stand upright in the bond well so it is ready for use at any time. This eliminates brush wastage and the possibility of cross contamination. Free standing, also includes an autoclavable base (one per pack) that can be used to lock the legs into place and ensure a high degree of stability. Disposable.
