These natural umbonium shells are great for all your shell craft projects. They range in size from approximately 1/4" to 1/2". You will receive one 3" x 4" bag full, that's about 1/2 cup, hundreds of shells. I love the patterns that these shells have naturally, they are gorgeous. They blend with the seashell pieces very well. I use them for borders on some of my crosses and frames (see the extra photo above). You will receive one bag of shells. Frame is not included.
