Yes, the title says it actually already, the labels are really good, the "opacity" I'd go with "2" mark, although it covers some lighter stuff, but if you, for example, prints a consignment label or cover the old label wants, at eg return, then you see the underneath lying still something. For me, but fully in order. The adhesive is strong enough, the labels have not parted with me by itself ... to glue the carton super! Only the price of 11.99 is a bit steep but for quality I pay the like, considering that there really are very expensive products that do not necessarily perform better. Conclusion: I recommend the item below! Super price / performance ratio
