Piquadro Credit Card Holder With Sliding System Yellow PP4825B3R/G

Technical specifications

Black Square backpacks, bags and accessories are made with full-grain Tuscan leather, tanned with vegetable tannins. Its non-homogeneous appearance is the result of an original artisanal process, washing, which preserves all the warmth and charm of natural, uncovered leather. After tanning, expert hands place the leather in large tanks full of water, without the addition of chemicals. The leather is then dried in drums and finally stretched out, so that its fibers release. Thanks to the experience of patient master tanners, the leather thus acquires those differences in color shades, grain and softness, which make each piece of the Black Square collection unique and exclusive.

Product testing

Watch the video of the laboratory tests

• pH determination test on the skin: allows you to determine the real pH value of the skin which must be between 3.5 and 4.5
• Oxidation test: establishes the propensity of metal surfaces to oxidize due to contact with skin or water. No oxidation is permitted.
• Color fastness test to water and sweat: serves to determine the color fastness of the product to contact with water and sweat. The possible transfer of color on the fabrics used in clothing is checked.
• Veslic test on leather: useful for determining the resistance of each leather to wear, abrasion or color transfer. The leather sample is tested both dry and wet and under a removable weight of 1 kg.
• Leather resistance test to stains: the leather's reaction to stains is determined by pouring small drops of water on its surface and checking every 30 minutes and after 24 hours. No stains, marks or waves on the leather are permitted.
• Metal finish resistance test: evaluates the resistance of the finish on the metal accessory by simulating normal deterioration. You make a cut with a cutter and see how the finish behaves.
• Salt spray resistance test: establishes the propensity of metal surfaces to oxidize or damage the finish due to the salt spray effect (fog at 47°C - test duration: 24h). No oxidation is permitted.
• Leather finishing resistance test: checks the resistance of the leather finishing. A layer of adhesive tape is applied on it and, after tearing it, the integrity of the leather is checked.
