Edge tapes and sealing: Hexagon stamp incorporates Japanese photosensitive pad edge sealing technology so the edges do not run ink, providing a cleaner stamp edge and better sealing performance. Hexagonal multi-message design: One hexagon stamp contains 6 pages with different words, corresponding to 6 distinct stamp impressions in a single tool. Quick, compact, and easy to rotate between messages. Washing ink (water-soluble): The ink uses water-soluble material—easy to rinse away with water and safe for use on skin, making cleanup simple and child-friendly.

Water-soluble ink protects clothing and skin and simplifies cleanup. Function and performance: Reliable edge sealing reduces smudges and ink transfer beyond the intended stamp area. Stamping action delivers bright, clear impressions suitable for classroom, home, and craft use. Ink is formulated for easy removal with water while remaining visible on paper.
