2. First Impressions & Packaging

The packaging is bold and eye-catching. The prominent text "大吉大利今晚吃鸡" (which translates to "Good luck, eat chicken tonight") is a direct reference to the popular culture phrase from the game PlayerUnknown's Battlegrounds (PUBG), signaling that this product is likely targeted at gamers and a younger, trend-savvy demographic . The text "绝他来年" is more abstract but can imply a sense of being "peerless" or "unmatched," adding to the product's bold marketing .

The inclusion of "可擦蓝" (Erasable Blue) is prominently displayed, making it clear that this is a key selling point. The cartridges are packaged in a simple blister pack, keeping them secure and visible.

3. Ink Quality & Performance

Ink Property	Rating (out of 5)	Details
Color	4.0/5	Standard blue – not too light, not too dark
Smoothness	4.0/5	Smooth flow – suitable for everyday writing
Erasability	4.5/5	Erases cleanly with a standard ink eraser
Consistency	4.0/5	Even flow with minimal skipping
Smudge Resistance	3.5/5	Erasable ink is water-soluble – can smudge if wet

Smooth Writing Experience: The 9011 cartridges are formulated for smooth ink flow, providing a pleasant writing experience without skipping or scratching. The ink is described as "Rich & Consistent," ensuring even color delivery throughout the cartridge's life.

Erasable Blue Ink: The erasable feature is a significant advantage for students, note-takers, and anyone who values neatness. The ink can be erased cleanly using a standard ink eraser, allowing for corrections without the need for correction fluid or tape. However, it's important to note that erasable ink is typically water-soluble, meaning it can smudge or run if exposed to moisture . This makes it less suitable for important documents or use with highlighters.

4. Refillability & Eco-Friendly Design

Refill Feature	Details
Type	Refillable ink cartridges
Method	Can be refilled with bottled ink using a syringe or converter
Eco-Friendly	Reduces plastic waste compared to single-use cartridges
Cost-Effective	Refilling is cheaper than buying new cartridges

One of the standout features of the 9011 cartridges is that they are refillable. While they are designed as disposable cartridges, they can be refilled several times using a syringe or a fountain pen converter . This makes them an eco-friendly and cost-effective alternative to single-use plastic cartridges. Most cartridges are made of plastic that can't be recycled, so refilling helps reduce waste and extends the life of the cartridge .

How to Refill:

1. Using a Syringe: Insert a blunt syringe into the empty cartridge and fill it with bottled ink .

2. Using a Converter: Attach a converter to the pen, draw ink from a bottle, and use it to fill the cartridge .
