The following methods can be used:

1. Throw: Hold the tail of the pen core and flick it downwards with a slight force several times. Generally, as long as the pen tip is not damaged, you can continue to use it.

2. Blow: Disassemble the pen core and blow air inward towards the end of the pen core. This is similar to the previous principle, which is to return the ink to the pen tip.

3. Replacement: If the refill tip is broken, you can replace the previously used refill tip with the broken refill tip and repeat the previous method.

Eight traps

Gel-in pens

Doing business should be based on integrity. However, due to the fierce competition in the industry, especially the cruelty of competition in writing and stationery, In order to survive, many manufacturers or dealers have to save costs, cut corners and compete for the market at low prices.

As a result, the quality of ballpoint pens and gel pens is poor. In Yiwu International Trade City, the unit price of a ballpoint pen refill is as low as 0.028 yuan; the unit price of a gel pen refill is as low as 0.10 yuan; some people who are new to the industry Due to lack of experience, friends find it difficult to identify the pros and cons of products, especially gel pens with high technical content and no national standards to follow. They often purchase some inferior products that cannot be returned, thus causing economic losses.

Based on experience and lessons, we list eight major pitfalls of ballpoint pens and gel pens. We ask friends not to be cautious when purchasing. We also hope that friends can give you more advice and share valuable experiences.

Trap 1: Many opaque ballpoint pen refills do not fill with enough ink according to the requirements of GB/T4306-92 (national standard), only 1-2 cm of ink near the tip; some transparent ballpoint pens The 1 centimeter or so of the core close to the tip of the pen is ink that can be written on, and the rest cannot be written on.

Trap 2: Inferior ink cannot be used within the ambient temperature range of 0-40°C required by the national standard. Ink will leak when the temperature is high; ink will not flow smoothly when the temperature is low.

Trap 3: The national standard requirement for the shelf life of ballpoint pens is two years, and inferior ink dries up in a few months.

Trap 4: The standard writing angle of a ballpoint pen is required by the national standard to be 47 degrees. An inferior pen tip or inferior ink can only write when it is vertical. If you hold the pen barrel at an angle, it will be difficult or impossible to write ( Holding the pen at an angle of about 47 degrees, in a counterclockwise direction, and making quick circles is a good way to directly test the ballpoint pen).

Trap 5: The barrels of ballpoint pens and gel pens are mostly made of plastic. The caps that fix the refills of inferior products can easily slip. The pen buckle and pen case do not contact the bayonet, and are not bonded with glue. , relying on the tension of the plastic itself, it is easy to fall off; the tail plug is also easy to pop off when writing with force.

Almost all of the production lines in these factories are paid on a piece-by-piece basis. Even if there is a quality system, there is no process or end-of-process inspection, and the quality system is in name only.

Trap 6: Gel pens are an emerging product. There is currently no national standard, and due to immature technology and production processes, ink is prone to agglomeration, thickening, crystallization and other phenomena. Many manufacturers work hard, especially for gel pens with a nominal 0.5mm or 0.38mm needle tube. Most products will not be able to be written after 3-5 months.

Trap 7: Not only does inferior ink not write smoothly or well, but it also spits out ink or bleeds. There is often no problem when you look at the sample, but after payment, the goods are not correct, and there are many problems. . (Gently and quickly draw a straight line at the same angle as the ballpoint pen. A good product has continuous lines, neither thick nor thin, and consistent color depth.

Then hold the pen at the same angle and use normal writing pressure. Slowly draw the polyline. A good product line will not accumulate ink or water seepage. When writing slowly, there will be no ink accumulation spots. It will not be thick or thin, and the color will be consistent. Then hold the pen at the same angle and make a quick circle in a counterclockwise direction. , a good product feels smooth and smooth)

Trap 8: In addition to the ink problem of inferior gel pens, there are also inferior materials for the ball, rough inner cavity of the pen tip, and insufficient oil in the tail plug. Following, the sealing wax ball of the pen tip is not elastic and seals well, etc. These will cause problems during long storage time or during transportation or use.
