The tool (basically a chunk of green plastic in the correct shape) is handy, but not necessary. With a bit more time it can be done with just the syringe.
The caps are a few cents each, which is fairly negligible, considering the cannabis oil is quite pricey.

RSO or rick Simpson oil correct or full spectrum cannabis oil

The stuff I just made isn't full spectrum because I used extracts to start with, not bud. But I make full spectrum RSO sometimes too.

It sure worked. We slept 8 hours straight after taking 1 capsule each last night. It has been YEARS since I slept 8 hours straight!

good to hear thanks this info helps I have relatives with some fairly severe aliments that also make it hard for them to sleep so I think ill give decarded concentrate capsules thanks for your feedback
