|use "shuniku" stamp pads for your rubber hanko|
First of all, you have to understand that rubber hanko are consumables. They do not last forever. To make them last as long as possible, however, you need to follow these rules:
|ink paste is no-no for rubber chops|
2) Do NOT use red ink paste to ink your rubber hanko. This is safe for chops carved from stone or wood, but not for rubber chops. The oils in the paste will cause your rubber hanko to get hard and brittle over time. The paste also contains particles that will stick in the grooves of your rubber hanko, and unlike the sturdier stone and wood chops, if you try to scrape such particles out of the grooves, you can easily nick your rubber chop and ruin it.
Get yourself a shuniku stamp pad. They are cheap and have the same bright red-orange color that is traditional for using with chops. These pocket-sized stamp pads (or ink pads) are typically encased in round plastic cases with screw caps, or square plastic cases with flip-tops like in the photo at the top of this post.
