building a coolidor

Those appear to be the 70% Heartfelt beads.

I'd go with the 65% beads over the 70% but some people like their cigars better around 70% so it is all personal preference. If you want the 70% just go with what your local B&M has as they do appear to be the exact same. If you want 65% just order online. They are shipped in a padded envelope priority mail and only take a few days. In all honesty the box would be fine in the cooler without beads while the beads are in transit for a few days. Just don't open the box or if you do just put a moist sponge in the coolidor. This is not really good for long term storage but for the 3 days it takes for the beads to get to you it is no problem.
