Easy to control how much ink you put in when refilling the stamp.

Speed of delivery and quality

I have a pocket stamp which was running dry. I used a stamp pad to ink it up for a while, but that didn't work very well. I then bought this bottle to do it the right way. The instructions say to add just a couple of drops to each opening, which I did. The pad sucked up the ink instantly, but I didn't see any effect the next day. So I put in just another drop in each hole the next day, same result. So I then put three more drops in each hole the next day, and I saw some improvement, but not great. I then put in three more drop in each hole the next day, and finally it started to be a decent stamp. Fortunatey, I stil have some left for tomorrow.
