Lanvin x H&M leopard crystal tie heels

Brand new with tags Lanvin for H&M leopard with crystal and black tie heels ***there is some discoloration on the jewels - these have never been worn and kept in the box. just noticed some jewels turned yellowish (see photos). it seems to only be on the right heel. more noticeable in the video than in person in my opinion. Great collector item! Size EUR40 which is 9US on the box
