The IQ Series stainless steel dosing capsules are a great addition and can be used for easy loading on the go, dosage metering, keeping the oven cleaner or even conserving herb. The 304 stainless steel dosage pods hold up to .3g of flower, concentrate or a combination thereof. This threaded dosing capsule will make loading on the go a breeze, and due to the thermal properties of steel, the stainless steel dosing capsule heats up 16% faster than the ceramic version. DaVinci's Stainless Steel Dosing Capsules pair well with the Dosing Capsule Herb Grinder which can fill all six of these capsules as you grind. Compatible with IQ, IQC, IQ2, IQ2 Carbon Vaporizers
