Purchased at the Namba Takashimaya CHANEL boutique. Spare button that came with a coat or jacket. This is a bijou button. It's vintage, from around '96. The jackets and coats that came with these buttons were quite expensive, so perhaps someone lost one? As it's a vintage item, they are no longer in stock at the CHANEL boutique. 1.5 cm, 1 piece. There is a CHANEL engraving on the back ☆ Since it's a spare, it's like new, but it is an aged item, so please refrain from purchasing if you are sensitive.
