I've been using the Kokuyo Dot 'N' Roller for years and recently found out that it will no longer be available in the US. I was very happy when I received the Tombow Dots Roller and found it to be almost identical to the Kokuyo and a little cheaper too! I would definitely recommend this to Kokuyo users who are looking for a replacement product.
Sometimes if you do not hold it just right you will not get a solid line, but it you really pay attention it works well
I purchased this because I like Tombow. This is good adhesive. I love that it is refillable.
