These incense sticks are of top quality and I'm sure they have used high quality essential oils in it. These sticks smell nothing like those low quality agarbattis we get in market. The fragrance is very smooth and soothing, people who are alergic to scents won't mind this, burn time is pretty good ,burns for atleast 30 minutes and the fragrance lingers around for good 2-3 hours and makes your home smell like a zen temple. Though bit expensive but worth the price.
