The XL-sized bookmark is perfectly suited for loose-leaf works with a text block width of 86 mm. This includes, for example, the Habersack - German Laws - Text Collection (from the 191st supplement), as well as many other texts. The MARK bookmarks from SKIN fit perfectly with Beck's loose-leaf works. To use it, simply slide the plastic end between the text block and the cover. This allows the 7 markers to be conveniently placed between the pages. SKIN has long been a manufacturer of many legal accessories and the inventor of the original Habersack bags, which have been refined over the years. Since 2004, new shapes and materials have been experimented with, questioning the norm and exploring new paths. However, one thing remains the same - quality and durability take precedence at SKIN.
