STORING YOUR DELTA 8 THC DISTILLATE
If you do not use the delta 8 THC all at once, you may store if for future use. For best results, we suggest wiping the dispensing tip of the syringe with ethanol or another solvent you are capable of safely using to remove any bits of delta 8 THC after use. Then re-cap the syringe and store in a cool dark place for future use. A refrigerator is a good option, but note that this may result in longer thawing times for your next use. If you re-cap without cleaning off any extraneous delta 8 THC, it may be hard to get the cap off the next time you use it.
