These specially designed packagers enhance the simplicity and packing capacity of Ultrapak woven thread. The fine tips are inserted into the woven thread, and their serrated edges prevent the instrument from slipping and cutting the gingival insertion. The serrated instruments are ideal for axial packing of these threads, while the non-serrated sliding packagers are more suitable for horizontal sliding movements. Both packagers are available in two sizes, and their tips are angled at 45º relative to the handle, to the right and left respectively, allowing for circular packing of the preparation without the need to rotate the instrument to use one end or the other.
