We have been an authorized dealer for Cigar Oasis products for 20 years! Cigar Oasis units were designed to make life easier for the cigar smoker. This is the 30" long replacement ribbon for the 3.0 versions of the Ultra, Excel and Plus units. These are very desirable if you have a small cabinet or foot locker type humidor where the 12" standard 3.0 cable is too short. This does NOT work with the legacy Cigar Oasis models that have 3 wire gold or orange ribbons or the 2.0 models that have the white 10 pin ribbons. Please check with us if you are unsure which long cable you need for your Cigar Oasis humidifier.
