Monotone Shells Sizes Vary Bulk purchase of shells - shipping discount available! Free shipping on one item when you buy two. These are natural items, so there may be some scratches and dirt. They have been cleaned, but sand and stones have not been removed. Considering these factors, I am offering them at a bargain price and will ship them directly in an envelope without cushioning material. I cannot be responsible for breakage during shipping, and I do not accept returns or cancellations. If you are okay with this, please consider purchasing.
