This is from Bryan
The entire Scarabeo model is made in Vitellino Lisse, enhanced by a new technique. The Fettuccia used is padded at the center to intensify the iridescent effect. The name Scarabeo was chosen because of the final effect reminiscing a scarab's shade and color variations. The special iridescent effect enhancing the top of the bag, along with the handles, is done through a long [handmade] process: a metallic pearly color is sprayed on to create the iridescent effect [color changes depending on the exposure to the light], then multiple passages are required for the iridescent look and then again to fix it and create the glazed effect.
Extremely hard to capture and more beautiful IRL i am told!
