Afternoon ordered, next to me tomorrow. I only know of express deliveries. First look -only 75gr - test the same. Two-sided printing with color laser (Samsung CLP-310) brought good results. Translucence of the reverse only (as in 80) with backlight. It was a flyer with heavy ink coverage on both sides. Not only for letters with borderline weight. Conclusion: the Note (75gr) should be safely located in the item name. One or the other might just looking for this property.
