Product Name: Stirling Engine Model
Color: As shown on the picture.
Material: Metal,Glass
Usage:
1. Security start step
(1) Put the engine model in a horizontal position.
(2) Turn the flywheel gently with the hand, check whether the flywheel is running smoothly if there is a strong sense of astringency, check whether the connecting rod is connected to normal, whether the piston in the air cylinder and the spindle on the copper sleeve have oil if there is a dry cloth or toilet paper with oil. Wipe the piston and the outer wall of the spindle, confirm that there is no oil stain or foreign matter to ensure that the flywheel runs smoothly.
(3) Check whether the two crankshaft angle on the flywheel is 90 degrees (the crankshaft is at the bottom or the most right side of the crankshaft at the bottom), if it is not to be adjusted in parentheses.
(4) The alcohol lamp is moved to the hole of alcohol lampholder, and the alcohol lamp is ignited on the premise of confirming safety.
(5) After heating for 60 seconds, start with your hand gently toggle the flywheel until the flywheel can run automatically.

(2) If alcohol is inadvertently sprinkled on the model floor or on the desktop, please wait for the alcohol to evaporate completely or dry the alcohol, and then ignition.
(3) The wick of the alcohol lamp can not meet the test tube, and the light core will produce water vapor when it burns. If it meets the test tube, it will break the test tube.

Insane Value Loafers
Size: 8, Color: Tan Faux Leather
These loafers are seriously impressive for the price. They’re as nice as my $80-100 pairs for significantly less. Super comfortable, great material, and holding up well 6 months later.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.
