Perfect for our classroom supply closet

Bought this bucket for my third-grade class. The variety of colors is great, and having 100 pieces means we won't run out all year. The cartridges fit perfectly in the standard pens we use for handwriting practice.

Convenient bulk storage

The bucket packaging is sturdy and keeps the cartridges organized. It's much better than buying small packs repeatedly. The blue-black ink is particularly nice for formal school assignments.

Smooth writing for beginners

These refills are ideal for kids learning to write. The ink flows smoothly without blotching, which helps maintain good posture since they don't have to press hard. Highly recommend for parents.

Essential for tutoring center

We go through ink fast at our after-school program. This wholesale pack is a lifesaver. The cartridges are easy for children to replace themselves, promoting independence.

Good quality, fast shipping

Arrived quickly and well-packed. The ink colors are vibrant and true to the description. My only wish is that they offered a pure black only option in this size, but the mix works fine.

Great value, minor leakage on one

Overall excellent bulk pack. My son uses these daily for his homework. One cartridge had a tiny leak, but with 99 others working flawlessly, it's still a fantastic deal for the price.

5 FAQ

Q: What is the shelf life of the ink in the bucket?

A: If stored in a cool, dry place away from direct sunlight, the cartridges typically remain fresh for up to 3 years from the manufacturing date.

Q: Are these suitable for left-handed writers?

A: Yes, the quick-dry formula helps prevent smudging, making these cartridges an excellent choice for left-handed students who often drag their hands across wet ink.

Q: Do these cartridges fit Parker-style pens?

A: No, these are specifically designed for 3.4mm direct-liquid fountain pens commonly used by elementary students, not standard international or Parker-style converters.

Q: Can I buy just the black ink cartridges?

A: This specific SKU is a mixed-color bucket pack. Please check our store for single-color refill packs if you require only black ink.

Q: Is the ink washable if it gets on clothes?

A: While the ink is safe for general use, it is designed to be permanent on paper. We recommend treating stains immediately with cold water, but results may vary depending on fabric type.
