Low-Temperature Stirling Engine Coffee Cup Engine Model Desktop Toy GiftsFeatures:
.LTD Stirling Engine: Mainly made of metal, the dreamy and eco-friendly machine model is exquisite, aesthetic and rich in metallic luster.
.Simple Operation&Easy Use: Put it on a water cup or coffee cup with a water temperature above 90 degrees Celsius, then turn the flywheel into a magical operation after half a minute of preheating for an enjoyable toy on your desk.
.Build to Last and Continuous Running: The durable and sturdy engine works silently. It will run continuously and permanently, as long as the temperature difference is enough, which is capable of placing on your desk and office table for a long time.
.Wide Application: The affordable and stunning model can be used for scientific laboratory projects, energy conversion&dynamics studies and teaching demonstrations. It is also available as an astounding toy and talking point between you and your friends, and everyone will wonder how it works.
.Ideal Gift: The Stirling engine is a perfect birthday or Christmas gift to surprise friends, family, parents, and children, a delicate toy for model collectors and an incredible teaching tool for school teachers.
.Notes: You only need to fill the glass by about half. If there's a bit of mechanical noise, just lubricate it with a little graphite to quiet it down. You can scrape the graphite off a pencil with a knife. Do not lubricate it with oil for the oil will mix with dust in the air to form greasy dirt, which will give the Stirling engine too greater friction to run freely.

Perfect case for my daughter’s iPad
Color: Purple Pink
bought this case for my daughter.
The fit is perfect — all the buttons and camera line up exactly and it snaps on securely.
The case feels sturdy, protective, and durable but not too heavy, so she can still carry it comfortably.
The stand feature is convenient. The design is also super cute — Luna loves it
Overall, great quality for the price. I would definitely buy it again

Perfect case
Color: Purple Pink
Great protection for my IPad. I’m always dropping something. This case was pretty easy to install and has the protection over the glass front. No problem using the iPad with the cover. Cute colors and has a loop to store the pen
