PILOT Frixion Synergy Knock x Anna Sui 0.5mm

Experience elegance and precision with the FriXion Synergy Knock × ANNA SUI limited-edition gel pen. This version features a 0.5 mm tip for smooth, confident writing — ideal for daily journaling, note-taking, and creative writing. Thanks to the innovative Synergy Tip, you get the best of both worlds: precision of a needle point and durability of a conical point.

Powered by Pilot’s thermo-sensitive FriXion ink, the pen lets you write freely and erase flawlessly — just rub the built-in eraser to make your mistakes disappear without smudging. All four variants in this collection share the same black FriXion ink, while the barrel designs are inspired by ANNA SUI’s signature fantasy motifs: magical butterflies, starlit gardens, and dreamy purple roses.

Designed in limited quantities, these pens are not just practical tools — they’re collectible expressions of ANNA SUI’s “Secret Garden” world, making them perfect for fans of fashion, stationery lovers, or thoughtful gift-givers.
