Review on MG Chemicals Thermal Milliliters Dispenser by Adam Bates

Worked for my needs. Easily done with a small knife or tiny spatula. It can also be in a syringe. A noticeable odor appears on the first or second heating, but the odor disappears fairly quickly. If you're working for others, you probably want to heat it up to get rid of the smell, or at least let the end user know it's "normal" so they don't think something's on fire.
