These brown, striped shells are great for adding a border to your shell craft projects. They have a very unique pattern, hard to believe its natural, but it is! They range in size from approximately 3/8" to 3/4". You will receive one 3" x 4" bag full, that's about 1/2 cup, hundreds of shells. I have used them on my wall crosses, seashell flowers, bathroom sets, and sometimes as accents on some of my shell art.
