See, that's what you'd think. It's not at all true, though.
When a person uses things for purposes which they are not intended, bad things happen. A cigar oasis is very oversized for a desktop humidor. It's mere presence and construction can (and will) easily run a desktop humidor over 80% humidity, never allowing the humidor to recover a lower setting. That's when mold grows and ruins your cigars.
You haven't stated the size of your desktop, and you've been given a number of excellent suggestions. If you want to lean on hundreds of collective years of experience, it helps to give the information that's asked of you.
At that point, the guys can help, let you know what to expect, and help you avoid creating a bigger problem for yourself.
