These are quite sturdy and thick seashells! The smallest is 5.5 cm and the largest is 7.5 cm. Four out of nine have holes in the bottom! (See image 2) The first image has too much light... The actual colors are closer to images 4, 5, and 6. Also, the colors may differ depending on your phone. I will wrap them in bubble wrap and take care to prevent damage during shipping, but there is a possibility of chipping. Please understand this before purchasing. As these are natural items, some may have original scratches, so please check the images and I will not accept claims. These are discounted due to the imperfections! Perfect for handicrafts or summer vacation projects! I have other types of seashells for sale, so please take a look. Bulk purchases are welcome!
