How to identify the authenticity of a box of Changbai Mountain Fine Tobacco 15% as follows:

1. The authentic "Changbai Mountain" font uses embossed hot stamping technology, and the uneven feeling is obvious when touched by hand. The fake "Changbai Mountain" font has no obvious concavity and convexity when molded by hand.

2. The genuine trademark paper is made of transfer silver cardboard. The fake ones use high-definition scanning and imitation printing.

3. The adhesive used to seal genuine trademark paper is white latex, and the glue dots are regular in shape on the left and right. The fake trademark paper is sealed with ordinary glue, and the shape of the glue dots is irregular.

4. The red printing on genuine cigarette trademark paper shows dense and uniform traces of fine particles, giving it a frosted feel. The Changbaishan font and trademark pattern on the pull line are clear and bright. The fonts and flower patterns on the seal paper are "gold" and bright, and the fonts are clear. The fake trademark paper has red printing without traces of fine particles and is visually smooth. The color of the pull cord appears white, and the font and trademark pattern are dim and blurry. The "gold" font and pattern on the seal paper are dull and dull.

5. The shape of the thread puller of genuine cigarettes is a full semi-elliptical shape. The soldering iron marks on the transparent paper are wide and obvious. The Changbai Mountain pattern and logo pattern are super-printed on the trademark paper, which is bright and clear when viewed from the side. The fake thread puller is long and thin in shape and rough cut. The soldering iron marks on the cigarette transparent paper are narrow and close to the edge. The Changbai Mountain pattern and logo pattern printed on the trademark paper are blurry and incomplete when viewed from the side.

6. The transparent paper of genuine cigarettes shrinks evenly and naturally when sealed, and there are traces of soldering iron. There is a large gap when folding the corners of the label paper; the bottom label paper cannot be glued to the edge, and there will be gaps at the edges. The fake transparent paper shrinks more chaotically when heated and seals, and the water vapor is heavier. The corners of the trademark paper are tightly folded and there are no gaps; the edges of the bottom trademark paper are leaky and there are traces of glue spillage.

I hope the above information is helpful to you.
