Each packet has a mix of 25 pieces, varying in size, shape, texture, and color but all are made from plastic/lucite. Cabs may be very small to large and may be round, oval, or even square. Pieces may have a high dome to a very low dome to a textured surface. All packets are similar, but vary in content. These are great for placing in settings for jewelry, adhering to jewelry findings, using as a craft embellishment, etc. You may or may not receive pieces in the picture as there are far more different cabs available than what is shown (small cabs weren't instock at the time of the photoshoot)!
