The Steampunk inspired artwork on these cufflinks has been printed using archival inks and papers and protected with a crystal clear, high gloss unbreakable resin which beautifully enhances the image below. Our handcrafted cufflinks measure 16mm (0.64inch) each in diameter and each pair sold includes a gift box Our pendants are water resistant but not completely waterproof. Great unique gift idea. Very popular gift item for men for Fathers Day.
