Spiral filters (x6)

The "spiral" filter for your pipe:

These aluminum filters are made in Saint-Claude (France). They'll allow you to replace your filters that are worn-out or broken. 

They will fit any pipe that has a 3 mm or 4 mm drilling, whatever the brand. Hence, they won't fit pipes that are meant to be used with 6 mm or 9 mm filters.

How to put the filter in:

These metal filters have an "adjustable" part: if needed, you can spread out the two strips, so that the filter fits correctly in the tenon. By doing so, the filter will be adjusted to the stem's diameter (3 or 4 milimeters). 

A pack contains 6 identical metal filters.
