In terms of formulation, we select high-quality tobacco leaves that are aromatic, with moderate nicotine and low tar content, both from domestic and international sources. These are meticulously blended, ensuring a harmonious balance of chemical components, complemented by special high-quality imported flavoring agents, which guarantee a distinctive aromatic style and character. Measurements show that the ratio of tar to nicotine is maintained at a reasonable range of approximately 10:1, with tar content further reduced, resulting in a smoother and more delicate smoke. For packaging and auxiliary materials, the trademark and box are printed on environmentally friendly aluminum-coated paper with a laser background. The entire packaging features a subtly shimmering laser font for “利群” (Li Qun), enhancing the brand's visual impact while serving as a highly effective anti-counterfeiting measure. The packaging design employs an elegant color scheme of dark and light shades, while the factory emblem is printed with invisible dual-band ultraviolet ink for added security. The paper used for the cigarettes is a soft and delicate pearlized paper, with the brand name hot-stamped in gold at the bottom, giving the cigarette appearance a more reasonable and harmonious look.

在配方上，选择国内外香气足、烟碱适中、焦油含量低的优质烟叶，精心配比，在化学成分比例协调的基础上，配合特殊的优质进口香精香料，保证其突出的香气风格和特征。经测定，焦油和烟碱的比值保持在10∶1左右的合理范围，且焦油量进一步降低，烟气更加柔和细腻。 在包装和辅料的选择上，商标及条盒采用镭射底纹环保型的喷铝纸印刷，整个包装体以暗显闪光镭射字体“利群”反衬主题，既增添了品牌的渲染力度，又是极难伪冒的防伪手段。包装格调以原三段间色为上下二色，颜色搭配高雅大方。厂徽标志用隐形双波段紫外油墨防伪。水松纸采用柔和细腻的珠光水松纸，并在下方烫金印刷牌号，使烟支外观更趋合理、协调。
