Astromedia 20cm Newton's Window Prism with Hanging Loop for Ages 10+This large crown glass prism projects beautiful spectral colours into your room. Hang the prism in a south west or south east facing window. When the low standing sun shines through the prism, it projects fields of spectral colours sideways into the room. A slight spin of the prism makes them dance around beautifully. The English mathematician, physicist, and philosopher Sir Isaac Newton (1643 1727) was one of the founding fathers of the modern theory

Order by them selves
Flavor Name: Americana
Great product, dogs love them. Be careful not to order with heavy items, as Amazon zombies will box them up with such items as Hint flavored waters. Image potato chips at the bottom of a paper grocery bag and a gallon or two of milk on top.

One of my dog’s favorites!
Flavor Name: Americana
I repurchase these training treat chips for my dog over and over again. I usually buy the chicken flavor but my dog also loves the turkey and beef. So far the quality has been very good and very consistent. My sensitive dog has zero issues consuming these treats and is always happy to be rewarded with them. Highly recommend.

Great treats/Terrible shipping
Flavor Name: Americana
Great single ingredient product, almost always arrives in broken pieces as it is shipped in a bag. Advertisement says "easily broken" so they can be used for smaller training treats, not only are they easily broken but they likely will be on arrival.
