Big: the largest size
Big measures 14 × 40 mm and is the largest size in the range.
How to choose
Match the filter to your paper. A wide filter in a narrow paper doesn't hold well, so check the paper you use first. Not sure where to start? Our rolling papers guide explains the papers, and our filter bundles combine filters with papers in one set.
