ADOX Snap-On 85B Gelatin Filters are filters made with a patented shape that uses little teeth on the side to "bite" the inside of the lens filter thread. If necessary, you can press or screw them in a little. For removal, simply pull on the info tab, where the filter type and exposure factor are printed.
ADOX gelatin filters are made in coating facilities in Switzerland from the world famous Cibachrome (R) dyes which are light stable and will not fade out. The coating makes the filter water resistant so they can be wiped clean with a wet cloth.
