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.
(6) The whole process of heating must not touch the main cylinder (high temperature danger!).

(3) If the engine model is cooled down naturally, please keep the engine where the child can't get it.
(4) Children should use the engine model under the care of adults, so as to prevent scalding or accidentally breaking the glass.
 
3.Matters of attention
(1) When alcohol is added to the alcohol lamp, please confirm that the alcohol lamp is in the state of extinction.
(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.
(4) The engine model has high rotational speed and will vibrate when running, so be careful to slide down from the table.
(5) Be careful when heating, prevent scalding.

Very nice linen suit for boys. Well worth the piece
Color: Beige, Size: 12
This JPF Double Breasted Linen Suit for Boys is the cutest thing I've ever seen! I got itt for my 8 year old and he loves it! He tried it on at soon as we received it and wore it all evening. Lol. He looks so grown up! He's about 4'3", about 75lbs. I ordered a size 12 and it fits him the way I'd expect it to. A bit big but he has room to grow into it. It is a 2 piece suit, with pants and blazer only. It's a summer suit, it's meant to have a more laid back, casual style. It is so nice! The style and color are identical to the photo. I got the beige color, that's the color my kid picked. I do worry a bit about staining, considering an 8 year old boy will be wearing it, but hopefully any stains will be easy to remove. The quality is excellent and the price isn't bad either. I highly recommend this suit

A charming summer suit
Color: Light Grey, Size: 6, Color: Light Grey, Size: 6
This suit fit true to size. The light grey wasn’t exactly the same as advertised (see photo), but I still really like it. My son felt snazzy in this suit, and he said it was comfortable to wear.

Nice suit for the price!
Color: Light Grey, Size: 12, Color: Light Grey, Size: 12
This really is a very nice boys suit, especially for the price they are asking. My kids don't wear suits too often, maybe once or twice a year for special occasions so I don't need really expensive suits for them. The material is actually really nice on this. The color looks great and the pieces are sewn nicely. The adjustable waist band is really nice on the pants because my kids are on the slimmer side and this helps with fitting. You can also wear a belt with these if needed. I washed on delicate cycle and dried on delicate cycle a little, then finished by air drying. They washed and dried very nicely with minimal wrinkling. The front pockets are real and useable on these, which isn't always the case with boys suits. Overall would 100% recommend

Nice looking suit that runs big
Color: Light Grey, Size: 6, Color: Light Grey, Size: 6
This is a beautiful light, gray linen suit size 6. It looks high end and it is a baggy fit, not slim. This suit is double breasted with a satin lining inside. There are two pockets in the jacket and one small smaller pocket for a handkerchief on the jacket. I did order a size 6 but this fits way too big for a size 6 I’m thinking it was more like a seven or an eight. The pants have a zipper, which moves very easily and 2 pockets. The Pants have belt loops. Both the the pants and jacket are longer than normal. My son is tall, so I was really surprised that these are so baggy and so long. I would definitely double check the size. there’s no size chart online so maybe I would go one size down. It does look like a quality made suit. The sizing is just off.
