Quadrum that I use aren't air tight. Their marketing is saying their plastics prevent oxidization, which seems to work.
I like them because they store easily and also present well (read: collectors pay a slightly higher price when they see quadrum).
Any recommendation of getting bulk pricing for those intercept capsule? I usually get from rennicks in NSW.
My experience with the normal quadrum and airtite is that quadrum open up easily
Need some feedback from the stacker out there.
What are your thought on quadrum capsule vs airtite capsule?
I like the quadrum design as it allow you to keep different size together but just not sure how air tight they are compare to airtite.
Square vs Round , both doing similar job.
There are different brands; but if the coins comes in OMP then I will leave them in the original holder.
In the end it comes back to space ; spaces that takes so much room, let not try to introduce more types and create headache to yourself.
Airtite are generally from U.S. and can be expensive. ( so many sizes there to stock up )
I do get my Quadrum from my local LCS and they are good supplier. ( same size thru out , but still so many sizes to stock up ) pro/con
Do you notice any difference in the coin between storing them in quadrum and airtite for long period of time? Does it tarnish/oxidise quick or no diff.
