FAQ

What materials can this corner rounder cut?
It features a sharp metal blade that cleanly cuts through materials up to 0.4mm thick. This includes standard journal paper (80g–350g), photo prints, business cards, cardstock, shrink plastic, and even laminated sheets, leaving a perfectly smooth edge without burrs.

How do I choose between the R4, R7, and R10 curves?
The 4-in-1 design lets you match the curve to your project scale. R4 is perfect for small journaling tags and business cards; R7 is the standard curve for photos and postcards; R10 delivers a deep, satisfying curve for large journal inserts. The fourth option (inner corner) creates a unique crescent cut for decorative borders.

Can it cut multiple sheets of paper at once?
Yes. The lever-action handle is designed for smooth, effortless pressing. It can comfortably punch through up to 4 sheets of standard 80g A4 paper in a single press without jamming.

How do I make sure the paper is aligned perfectly?
Simply flip the tool upside down. The transparent base allows you to see exactly where the paper rests against the internal guides, ensuring a flawless, perfectly centered cut every time.

How do I clean up the trimmed edges?
The transparent alignment base also doubles as a secure scrap tray. It catches and holds all your paper bits as you work, keeping your desk clean and ready for your next crafting session.
