Dutch Martin Martin Antheunisse is a Dutch craftsman who specialises in leather finishing. With over 30 years of experience he has developed a new type of leather for Secrid: Dutch Martin. Leather with a characteristic appearance and feel, developed and produced exclusively in the Netherlands. The coating is transparent and natural due to the use of wax, oil and grease. The hard carnauba wax makes the leather scratch-resistant and water-repellent. This gives it a natural gloss that deepens over time.
