Universal refills for popular pens

These Mega ballpoint refills fit many well-known pen brands, letting you keep a favourite writing instrument in service. Each pack contains ten black medium refills weighing 0.03 kilograms and measuring 3.9 inches in length. They suit everyday office, school and home writing tasks.

Simple drop-in replacement

Remove the old cartridge and insert the new refill until it seats firmly; no tools or adapters are required. The stainless-steel nib with tungsten carbide ball resists wear, while the quick-drying oil-based ink prevents smudging during immediate handling.

Check your pen before ordering

Verify that your pen accepts a 3.9-inch medium ballpoint cartridge of this diameter. The refills are not compatible with rollerball, gel or proprietary short cartridges, so buyers needing those formats should look elsewhere.

Questions about this item

How can I confirm the 3.9 inch refills write smoothly after installation?

Install a refill and write on standard paper; the medium point with three-point supporting tip should glide without skipping and the quick-drying black ink should not smudge when touched immediately.

What comes in the box and what must I purchase separately?

The pack contains 10 black medium ballpoint refills weighing 0.03 kg total; you only need a compatible pen body that accepts Parker-style refills, which is not included.

Which version should I choose if I want oil-based ink with a durable tip?

This single listed option provides oil-based black ink, a stainless steel nib and tungsten carbide ball in a medium point, supplied as a 10-count pack.
