I believe I purchased these seashell coasters in the Philippines around 2017. Because they are made of seashells, the appearance changes depending on the lighting, making them difficult to photograph. I think the top of the second photo is the closest representation of how they look. If you'd like, I can retake photos, so please feel free to ask. The surface appears to have been processed after the shells were applied, so the mosaic shell sections are not bumpy. However, as they are handmade, please understand that there may be slight differences between the two coasters. Also, I unfortunately damaged one of the cork bottoms when removing the price tag, causing a small chip. I don't think it will affect their use, but please be aware of this.
