Crystal Experiments & Crafts Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit. Experiment with four chemically different crystals each with different properties, including potassium alum crystals that form regular octahedrons, rapidly growing sodium sulfate crystals, long needle-shaped sodium acetate crystals, and plaster which is made from gypsum crystals. Mold fun plaster shapes, including stars, lightning bolts, dolphins, and pyramids, and grow layers of crystals on them. Use dyes to form colored crystals, and mix the dyes to grow a rainbow of custom colored crystals. Display your crystal creations in a clear treasure chest with a locking lid. Mold your own geode — a hollow rock with crystals growing inside — and create a beautiful crystal cavern inside. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow one giant crystal, and many small crystals on the surface of a rock. Measure how the crystallization of solids out of a solution, and the dissolution of crystals back into solution, affect the temperature of the solution. Learn about the energy of crystallization. Investigate solutions, crystallization, and the chemistry of crystal growing. Learn about the structures and geometries of different crystal shapes. This kit is thoroughly tested and safe: Over one million units of this kit have sold worldwide. A full-color, 32-page experiment manual guides your experiments in crystal chemistry and Earth science. #643522Shipping Notes

very poor quality
Size: 14, Color: Black
they are a peice of garbage, within about a month since i started wearing them the outer material started pealing off within two months the upper separated from the soles so i had to go to a shoemaker to sew them back together, within some few months the insoles completely wore out rendering the shoes unwearable, now mind you that i do not abuse shoes but use them in a normal office oriented enviorment, i will for sure not be buying these shoes again

Great wallet
Size: One Size, Color: Brown River Print
Nice quality wallet that holds all of my cards. It is thicker than I would have liked, but it is a good wallet. I like that it has two pockets for bills which is nice because I use other currencies. The card sleeves have three slots each. One sleeve on each half of the bifold and a middle one that flaps back and forth to show both sides. One side of the flap has the three card slots and the other side has the clear plastic for identification. There are also a sleeve under each of the three card slots. The wallet has a nice texture and a nice color. It feels pretty well-made and it seems like it would last a long time. It fits like any other bifold wallet.

Excelent quality
Size: One Size, Color: Black Passcase
I bought this Calvin Klein men’s wallet for my husband, and it exceeded our expectations. The leather feels premium and durable, with a sleek, minimalist design that matches any style. It’s compact enough to fit comfortably in his pocket, yet spacious enough for all his cards and cash. The stitching and logo details give it a touch of elegance without being flashy. After several weeks of use, it still looks brand new. Definitely worth the price — classic Calvin Klein quality and sophistication!
