on a box of 25 a wooden box it is on the wooden box...on the 3 pack a cardboard box it is on the cardboard but a much smaller version seal...i really dont understand your question.....i never saw a dress or cardboard box of 25 .safe to say the seal is always on either wooden or cardboard, always on the outside not the individual sleaves on the 3 packs.
I believe his question lies on whether the government seal is afixed directly to the wooden box or the cardboard sleve that some wooden boxes are shipped in (ie: H Upmann Sir Winstons, Partagas 8-9-8's, etc).
Just for future reference...
In the Cohiba Line, cigars are packed in the following.
BN (Varnished Boite Nature with brooch). These are the boxes the three initial 1982 vitolas came in, the Lanceros, Coronas Especiales and Panetelas. They can hold 25 cigars, placed in conventional layers, and their corners are softened. They come in a cardboard outer sleeve that contains the warranty seal, the Habanos chevron remains on the wooden box (top right).
SBN-B (Varnished Semi Boite Nature with Brooch). These boxes are used to hold two of the three 1989 vitolas, the Esplendidos and Exquisitos. The corners are sharp, and the lids are flat. Cigars come in two conventional layers. They have the warranty seal on the bottom right and Habanos chevron on the top left. They are then wrapped in glassine paper.
SLB (Varnished Slide Lid Box). This kind of box is used to keep the Robustos and also the six SIGLO Series vitolas. Cigars come in a bundle of 25 wrapped in a wide yellow cloth ribbon and a white glassine paper with a Cohiba self adhesive label holding the paper together. These boxes come with the warranty seal on the top left and the Habanos chevron on the lower right, also wrapped in glassine paper.
