1in less in diameter but taller from the specs I can find. Also no way that one holds 60+
It may be your office environment then. I have a 100ct Humidor at work... it's a PAIN to keep humidified correctly. The air in the office is amazingly dry and it just plain leeches humidity. I keep 2 Humigel jars and several boveda 72% in it and it's stable at 66%... and kills the bovedas pretty quickly so I have them recharging on a cycle...
If you're worried about looks - maybe go with a couple of these Jaridors?
