The filter holders have lost the little clip that holds them securely in place, hence the tape to make them secure.  I'm sure that replacements could be obtained, or a better fix.  One of the photos shows this missing clip.  This is the case for both filter holders.

This comes without the base.

Collection only because of the delicate nature of the item.
