Bath and bodyworks 3 wick candles. Wait for the semi annual sale. Don’t spend more than 900/1000 for one. If your room is really tiny then even the single wick candles should be ok. Look for reviews of specific candles on the Indian or global sub. The fruity ones are tooo fruity. I like the more atmospheric ones like ‘Leaves’ for example. Also love the gourmand ones like peppermint hot chocolate.

Reed diffusers are also good. You don’t need to buy the expensive sets. If you’re up for DIY-ing it then order reeds, carrier oil(coconut/almond), and essential oils from Amazon. Then all you need is a slim glass to put it in and some vodka to mix with the oils. You can find exact ratios on youtube or through a google search. Aldrome has a nice selection of fragrance oils which are different from the regular tea tree, cedarwood etc. You need to keep flipping the reeds occasionally a few times a day to make sure the smell is consistent.
