Buying Guide for Indelible Ink Pens For Writing Checks

Why I Choose Indelible Ink Pens for Checks

When I write checks, I want to be sure the ink won’t fade or be tampered with. Indelible ink pens provide that security because their ink is designed to be permanent and resistant to water, chemicals, and erasing attempts. Using these pens gives me peace of mind that my financial documents remain safe and legible.

Key Features I Look For

First, I pay attention to the ink quality. The ink should be truly indelible, meaning it won’t wash away or lighten over time. I also consider the pen tip type and size; a fine or medium tip helps me write neatly and clearly on the small spaces of a check. Additionally, the pen’s grip and comfort matter since I often write multiple checks at once.

Ink Color Preferences

I usually prefer blue or black ink because banks typically require these colors for checks. Blue ink also helps me easily distinguish my original signature from photocopies. It’s important to confirm the ink color is accepted by my bank before making a purchase.

Durability and Drying Time

A pen that dries quickly is essential to me to avoid smudging. I look for pens with fast-drying ink that remains vibrant and does not bleed through the paper. Durability of the pen itself is another factor; I want a sturdy pen that lasts through many uses without leaking or drying out.

Price and Availability

While I don’t mind spending a bit more for quality, I also consider affordability and availability. I tend to choose pens that are easy to find in stores or online so I can replace them without hassle.

My Final Tips

Before settling on a pen, I test it on a similar paper to check how the ink behaves. I also avoid gel or erasable pens since their ink is not permanent. By choosing the right indelible ink pen, I ensure my checks remain secure and professional-looking every time.
