Poly-cone liner

I am getting ready to order some amber glass storage bottles for the darkroom remodel.

How important is it that the phenolic cap has a poly-cone liner as opposed to a regular seal?

Thank you in advance!

It depends on what you're going to store in there. Also, what matters is if the seal is tight, not whether it's poly-cone etc.

The original Polycone lid was a patented high tech marvel. If you want to reuse the bottles buy the best closure. I use Polycone lids or Nalgene lids. Avoid anything that has a paper covered with foil liner.

Amber bottles look cool, clear glass has the advantage of being able to see when they are dirty or contaminated.

I have too many bottles
