There are two types of red ring needle pens on the market

Are you a student? I've sold red ring pins. The shop I made was Red Ring's.

I would like to give you a more pertinent suggestion. If you want to sell irrigation, the ** on the market now is estimated to be as low as 230, and it is generally sold for about 270, 230 I mean wholesale, more than ten sets. The contents include three needle pens, and the specifications are three.

A compass. A bottle of ink. A red-ring automatic pen and a box of red-ring leads.

If you buy the contents of this set separately, the market** may be able to sell for about 170, and the lowest is 120, if the store does not provide you with cleaning services. There will be problems. Because it's particularly easy to block.

If you don't use the potion for washing the pen, it is sometimes not easy to wash well. There are also special instruments for washing pens. Generally, regular shop owners have been trained in the work of washing pens in places such as Nanjing or Hong Kong.

There are two kinds of sets on the market that are more common, one is an old model, the store will strongly recommend it to you, and the advantages are clearly visible, but as far as many people in the design institute are concerned, the performance of the old model is still better. It's all the same. There are also other styles, excluding compasses without automatic pens and so on.

In addition, the 0'5 is not easy to break, and the kind that buys the black pen barrel is fine, and the kind is cheap. Fifty or sixty bar, if you buy it alone. Or replace the entire set of the set with a black pen barrel The ** can also drop by about 20 yuan.

Hehe, I don't know how to do it. Give you a description and you'll know.

Do you want to buy disposable or irrigation?

I advise you to buy a disposable one. It's less than 20 yuan. Irrigation should also be cleaned regularly. It must all be above 100, right?

This thing is a consumable. The disposable ones are actually more comfortable to use than the irrigated ones. And the red ring irrigation disposable ballast pen has one that I've been using for 5 years, and it can still be used. You can imagine how solid it is.

Even if you use it regularly, it won't be a problem to use it for 3 years. And you earn more money later.

After that, you can change whatever you want.

It's super easy to block.,It's recommended to replace it if you buy a set.,Mine is very blocked.。

Look at the nib, whether it is fine or not, you can know that China cannot manufacture a permanent needle pen. Therefore, the red ring is basically genuine permanently. If there is a fake one-time, I generally look at the printing quality and whether the rotring logo on the pen clip is upright, the edges are clear, and you can directly see the internal ink, which is very durable.

However, it is recommended that you buy a one-time one of Shi Delou, and the red ring is a little thick. Shi Delou's nib is very tenacious, the line type is the most standard, the ink is more conservative, the fakes that have not been seen at present, you can buy a set of boxed ones for ** 65, there are 6 sticks inside.

At present, there are not a lot of domestic defense in the red ring, go to a regular stationery store or ** good evaluation of the store to buy it is **, three points,, and,,,,

Look at the logo first, then focus on the nib, and then look at the overall workmanship.

If it's rotring, it's generally not fake.

It depends on which one you buy.

Red Ring has a variety of syringe pens.

In fact, it is better to buy the Stead Building.

No need to wash, just fetch water. When you use it every once in a while, remove the white part from the back and put the tip of your nose under the tap for a while. Re-inking.

……I use it all directly, so I don't have any special requirements.

The red ring will be thinner than the domestic pen, because the domestic pen is not in place, and the effect cannot be achieved.

You can try the red ring, maybe about the same thickness as the lion, and you can try it in the store where you buy a pen, you can write it.

The focus of the needle pen is maintenance, and it must be cleaned when it is not used for a long time, so don't fill too much ink in it at a time. Use hot water to soak the pen tip part and try it, then rinse, then fill the ink, and shake it.

The ink flowing out of the tube pen is a result of air pressure and gravity. The air that enters the barrel comes from the nib during the pen movement. Small bubbles float from the nib into the barrel and then apply pressure on the ink.

The vent in the nib assembly equalizes the air pressure inside and outside the barrel, so that the ink flows out evenly. If the airway is blocked, air bubbles can't enter and ink can't flow out.

The blockage is due to the vibration of the pen, which expands the air, which allows the ink to enter the snorkel. Inside the tube nib is a thin wire tied to a weight, the only movable part of the needle pen, and when the barrel pen is tilted or vibrates, gravity moves the wire up and down, controlling the flow of ink and removing any small debris from the nib.

What is the fraction of your pen? If yes. 1 or.

13 or. If you are blocked, you must be very careful. I don't know if it's because of the unsmooth underwater or if it's not going into the water at all.

It is okay to use warm water. But the premise is that your pen has never been dropped, and you have never been shaken hard. Otherwise.

Hehe, your pen doesn't need to be cleaned at all. It's broken. Don't shake it too hard.

Otherwise, the 100 yuan will be shaken! Pour warm water into the pencil bag, shake it gently, and try it slowly on smooth paper. It's really not good, find a seller to deal with it for you.

I'm talking about these kinds. 1，。13，。

18 are prone to problems. The seller is regular, he has after-sales service for you, I don't know how you are. Here's what I'm going to do.

It is supplemented below. Actually, I sold syringe pens, and I cleaned them with pen nights. Since you can't wash it yourself, and you don't have a pen wash liquid, I'm assuming you can't buy a pen wash solution.

There is also no special cleaning pencil bag. And the monopoly there all use ultrasonic pen washers, and you don't have either. This way, you can go to the place where the glasses are cleaned, and they have ultrasound** instruments.

Through ultrasound**, if the tip of your pen is indeed not broken, I think it can be washed through logically. The principle of ultrasonic is to use a tiny but high-frequency ** first soak and then make the dregs ** very small, and clean it is generally OK.

And then add. It's hard to earn your best... Hehe, but I still hope it can help you. If you are in Dalian, I can ask a friend to wash it for you. Oh, generally they clean it for 20 yuan at a time. . . Hehe.

There is a special red ring needle pen cleaning liquid, the store that buys the pen should have, buy it separately, it is not cheap, but it is very effective, remove the pen head, put it in a disposable cup, pour some cleaning liquid to soak, see the degree of blockage, especially blocked can generally be soaked in a day and a night.

Three sticks sell for more than 190, which is inappropriate

But needle pens are not cheap in the first place. A Sakura brand needle pen, buy it in wholesale places to buy about 8 15 yuan There may be more expensive Specific**I forgot I haven't bought it for a long time...

At present, there are not a lot of domestic defense in the red ring, go to a regular stationery store or ** good evaluation of the store to buy it is **, three points,, and,,,,
