Single-cylinder Electromagnetic 6-12V 2A All-metal Engine Model ToyFeatures:
.Parameters: Piston Diameter: 10mm; Piston Stroke: 7-8mm; 6-12V 2A, support brush ESC, strong magnetic piston support positive and negative rotation, iron piston support one-way rotation.
.Cool Shape: Single-cylinder electromagnetic engine model, mini-shaped, the main body is made of metal, and the overall mechanical sense is full; the production is fine, ingeniously built, the parts are perfectly combined, and the precise production technology is demonstrated.
.Working Principle: The electrical energy is converted into magnetic energy, and then the magnetic energy is converted into mechanical energy to do work. According to the principle of magnetic repulsion and heterosexual attraction, a small amount of electrical energy is used scientifically to generate powerful magnetic energy. Mutual repulsion and mutual attraction within the set range, resulting in extremely strong repulsive force and attraction force, forcing the lower magnet to move, pushing the connecting rod to drive the crankshaft to rotate to complete the engine working process.

It is a good sunscreen, but if your skin is very oily, think again.
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I have tried many, MANY sunscreens, and this one is in my top 10, but not at the very top. Why not? Well, what I like about it is that you get a good amount for an excellent price. It's lightweight, but not extremely so, and this size can easily last you 3 months without any problem. However, while it's made for oily skin, it's not that light. After just a few hours of application, it can leave your skin feeling greasy, especially if you sweat easily. It doesn't leave a white cast, but it does leave a slight, shiny finish. Reapplying isn't very comfortable. If you use it just once a day, it's fine, but if you apply it more often, your skin will feel a bit heavy and oily. I think this sunscreen is better for specific occasions rather than for daily use. If I had to choose a sunscreen for daily use, I would pick one with a lighter formula, like Fusion Water from Isdin.

stellar sunscreen for face- sensitive skin friendly, feels good not greasy on, timeless
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I used to try out different brands and this is the one I've got to have for my face- safe on sensitive skin and just feels really nice and not greasy putting on, sometimes I get stuck borrowing so now I get a few and have them in various places. Also, I appreciate they don't change the packaging or add other versions so I can grab and always feels great and works on

Works great but does not hold up to sweat
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Dissolves with intense exercise then burns eyes and makes a mess, but otherwise works great.
