This large red abalone sea shell measures approximately 9 3/8 inches long by 7 1/4 inches wide by 2 inches deep. It weighs about 1 pound 4 ounces. The shell has not been cleaned with acid or a wire brush. It was only hosed off with water. This is its natural state. The photos were taken while the shell was wet, so the colors are more vibrant than they are when the shell is dry. To bring out the colors, apply mineral oil with a rag. Priority mail medium box cost is $18.40 within the United States. Overseas mailing is actual cost for Priority Mail International. First Class Mail International to Canada is $16.00. No handling charges. Combined shipping available. If the shell breaks during shipping, the buyer will be sent a similar replacement shell or receive a refund.
