These 420Science UV jars are the best way I know to store cannabis. I put a small size Boveda humidifier pack in the bottom and it keeps my meds fresh for months on end. When cannabis was legalized in Oregon I went a little crazy trying out new strains. I used a label printer to label the jar tops and had a couple dozen or more strains on tap at all times. Now I’m mostly into concentrates and have waaay too many jars. All jars have been thoroughly cleaned with iso and are in great condition. I’m selling these in 2 sets. Shipping is $12.95 for flat rate USPS Priority Mail within the CONUS. If you want both sets, shipping is free! SET #1 - 8 Small 50ml Jars - $60 These 50ml UV jars hold ⅛ oz of flower.
