I know that a lot of people have been looking for the refills for the original Kokuyo dot adhesive runner (the blue and white one). You can find them on Amazon. (Disclaimer: This is an Amazon Affiliates link. I get a small percentage if you purchase something through my link. Thank you for your support!)
This is still one of my go-to adhesives for small, intricate die-cuts, because the dots stick only to the die-cut, and the adhesive doesn't make a mess.
