This pre inked stamp is great for notebooks, diaries, sticky notes and presents. The stamp is pre-inked (with oil based ink) so that you do not need an ink pad to use. The ink of the stamp is waterproof so that you can paint over the stamp with non-permanent markers. The size is nice and compact to fit in a pencil case. Good for approximately 1000 impressions! Size: H61 × W61 × D19mm
