By now you may have discovered that Hauser is no longer making the Hauser bill 707 SF rollerball refill. It was a great refill and was included in many rollerball pens over the years, but alas, is no longer available.
So, what to do? What rollerball ink refills are compatible with the Hauser bill 7o7 SF? What is an equivalent refill to the Hauser bill 707 SF rollerball refill? Well, there are a number of choices. The good news is that most rollerball refills sold today are interchangeable and most are compatible with Hauser.
|For starters, the Schmidt Safety Ceramic Roller 888 and the Schmidt Safety Ceramic Roller 5888 are both compatible with the Hauser bill 7o7 SF. Hauser makes several models as well that will be replacing the 707, including the Hauser H4004 Rollerball Refill and will be available in either blue or black ink. The new official name is the Hauser Open TC 777F, which we are planning to carry. But, until then, please use the Schmidt Safety Ceramic Roller 888 F or the Schmidt Safety Ceramic Roller 5888 rollerball refills as compatible replacements.|
