Consumers should choose copper cores, but note that some of them are plastic, and only a "copper core" of copper is wrapped around the core. Nickel-plated nickel and iron nickel have almost the same appearance, but the price is very different. Generally, the copper strips are muted, the iron trifles are not muted, and the copper tricycles work fine. The iron triads are rough. When the ball type is installed, such as eccentric core, etc., it is not easily installed, and it is easy to go wrong during use. There is now a backhand scum. If the handle is lifted gently, it will be trivial. It is very convenient, but it is easy to put the key in the house.

Relatively speaking, when turning a paratrooper, the smaller the sound is, the better the handle is, and the vowel tongue should follow.
