Saves money on pencils

I bought these for my twin boys who go through pencils quickly. These extenders have significantly reduced our pencil consumption. Highly recommend for parents.

Perfect for my second grader!

These caps are amazing. My daughter used to throw away pencils once they got short, but now she can keep using them comfortably. The silicone is soft and doesn't slip.

Excellent grip aid

My son has trouble holding thin pencils, but this adds just the right amount of thickness and texture. His handwriting has actually improved since using these.

Best pencil accessory

As a teacher, I recommend these to all my students' parents. They are easy to put on, washable, and truly help children maintain a proper grip as pencils wear down.

Cute and functional

The designs are adorable and the kids love picking their favorite color each day. They fit snugly on standard pencils. One cap was slightly loose, but the rest were perfect.

Great quality, vibrant colors

Very durable material that hasn't cracked even after months of use. The colors are bright and fun. Only wish the pack came with a storage case.

5 FAQ

Q: Are the colors random or can I choose?

A: The 6-pack comes with an assorted mix of colorful designs selected at random. Specific color selection is not available for this bundle.

Q: Are the materials safe for young children?

A: Yes, the caps are made from non-toxic, BPA-free silicone that is safe for children to handle during normal writing activities.

Q: How far does it extend the pencil life?

A: It allows you to use the pencil until it is only about 2 inches long, effectively doubling or tripling the usable life of a standard pencil.

Q: Can I wash these if they get dirty?

A: Absolutely! You can easily clean them with mild soap and water. Let them air dry completely before putting them back on the pencils.

Q: Do these fit triangular pencils?

A: These caps are designed primarily for standard hexagonal or round wooden pencils. They may be too loose for triangular pencils.
