    Had alot of steps but the directions were easy to follow. Takes awhile to grow the crystals and they are not easily removed from the containers.

    Verified Purchase

    The package, when opened, appeared to have been tampered with. One of the dye packets was leaking and almost caused severe damage to the granite countertops in the kitchen. Overstock was receptive and quick to issue a return and refund.

  • Extraordinary Choice!
    Verified Purchase

    Incredible last minute choice for the grandchildren for the holidays. They were so enthused about getting this for Xmas they IGNORED the things they'd asked for to inspect and try it. Not pseudo-scientific but the real thing, and the kids were knocked out. Best money I ever spent at Overstock! They are going to keep me posted as to how the crystals are growing!
