HERMES Hermès Oval mother-of-pearl clip, brown design. - Brand: HERMES - Design: Oval - Color: Brown - Accessories: Box Approximately 12.5cm x approximately 4.2cm Thickness: Approximately 5mm I purchased this with the intention of using it as an accessory when wearing a wool stole, but I have kept it in storage without ever using it. I always used the Hermès duty-free shop in the airport when traveling abroad, so I purchased this at a duty-free shop as well. It is unclear whether it is mother-of-pearl or mother-of-pearl style. Since it is Hermès, I don't think it's "style".
