Wood and shell are natural, organic materials. Shell is susceptible to breaking while worn if dropped or knocked. Patterned wood, such as tiger ebony, can show a large range of natural variation in colour and striping. Carved hanging wood styles are also susceptible to breakage if dropped or knocked. Each pair of plugs is well matched, and we try our best to represent the product in the photos, but do expect that for wood or shell that has natural variations, such as tiger ebony, that there will be some differences in pattern between what is photographed and the product you will receive.
