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.
I absolutely love this product. I was a little skeptical at first. I use to use just double sided tape. Then I decided...why not. I might as well try one. I did and never looked back. I buy them by the six pack refills and sometimes (2) six pack refills at a time. They are great for adhering to cards and my scrapbooks. They are easy to use...and simple to change out with the refill. I will never look back...I love them.
