Non-stick Flexi-Tips are designed for use with sticky composite resins, acrylics, epoxies, sealants, lubricants and waxes. Flexible enough to produce fluid shapes but firm enough to compact and condense viscous composite material. Materials can be effortlessly picked up, applied, condensed, carved, blended, smoothed and textured. Create beautiful, dense restorations with no visible joints or voids. Flexi-Tips allow each layer of composite material to be firmly compacted and smoothed into the previous layer. Solid silicone tip. Stiffer and more durable than brushes. Faster and easier to use than rigid materials.
