I liked these highliters so much that I used them up and had to get refills. These highlighters do not bleed and you can still see the wording very well after applying. They're comfordable, easy to use, and the ease of finding the exact same items to order again was a breeze.
It's great to be able to have refills instead of having to buy a new marker. Just wish the refill packs came with an option to get more than 2 refills at a time. I use these extensively for my Bible as well as other books.
If you are aware of these refills, I assume you are already the happy owner of the retractable "pen." In my area (NE Ohio), good luck on finding these refills--especially if you want a quantity. The local stores are always out of some color--usually pink or yellow. If they have the pen, there are no refills. If they have the refills (usually about 3 of them) there are no pens. CBD is the answer. I can get as many pens and refills as I want, and after "pounding my head against the wall" in local stores that could not order for a single color, CBD is a blessing indeed. These are great markers/crayons, and they do not bleed through. And the service through CBD is fabulous.
These are the refills for the best highlighter I have ever used. I am a full time researcher and teacher, and an avid reader. I use these highlighters all the time, in every type of book. I will never return to other types of highlighters. These are, quite simply, the best highlighters on the market. I recommend them to everyone who asks.
