Lightweight oil that fits into a simple routine
I started using this oil as part of my regular skincare routine, mainly applying it to areas like my arms and face after showering. The texture feels light and spreads easily without leaving a heavy residue. I noticed it absorbs fairly quickly, which makes it convenient for daily use. It also has a mild scent that is not overwhelming. I like that it includes plant based ingredients, and it leaves my skin feeling soft after application.

Refreshing orange scent
These are effective at refreshing your disposal. When I am done cleaning up my kitchen I put 2 drops in the disposal side of my sink and briefly pulse the disposal to break open the drop. Don't run any water as this will wash away the drop and the fresh orange scent. I am very sensitive to perfume or floral fragrances - these are just the right amount of orange scent to make your drain smell fresh without the scent overwhelming the kitchen.

Easy to use and work great
These are great. Helps with odors and grease cutting. So easy to just drop a couple in after use.

They smell AMAZING!!
Amazing quality, they smell great, and they last quite awhile! I like switching between the orange and lemon scents, as it’s nice to switch it up! A great price for the quantity and quality!

Easy To Use
Easy to use product with nice scent. The scent is a bit lighter than I thought it would be, but I suppose you could use a couple at a time. Compared to other brands I thought a good value as you get more. Seemed to work well. Popped one in, ran the disposal and the smell seemed to be gone.
