There is a difference between molded Plastic pieces vs High Quality Acrylic Crystals.
Plastic beads are made from a mold with a product called styrene. While a more light-weight product, styrene can produce a lower quality, cloudier looking plastic bead. Often times plastic beads will have pieces of the mold still attached to create sharp edges and the seam is highly visable.
Our acrylic pieces are injected and virtually seamless and guaranteed to be clear and full of sparkles, all of our acrylic crystals are cut to resemble more expensive glass crystal beads. You can clean your crystals with Windex or warm water to insure a lifetime of clarity.
Cristalier acrylic crystals look like real glass crystals from a distance , only you will know they are faux.
Our acrylic crystals mix well with each other but we don't recommend mixing with other glass or lead items.
