Sanby x Yumi Kitagishi Self-inking Stamp

I honestly didn't even know this was a self-inking stamp at first! I bought it because it's so cute. I've used it to decorate letters and envelopes that I send to my pen pals. It has high quality ink that dries quickly. Once the ink runs out I plan on using it with a regular stamp pad. I'll definitely buy more designs if they are available.
