This is the perfect single serve bag for medical cannabis flowers, edibles, or concentrates. It also works well for packaging small pharmaceuticals and herbal supplements. This bag measures 2 1/2" x 3 1/2" in (outer dimensions) and its matte white color renders a simple, plain bag that small children will find uninviting. A high metallized barrier prevents water vapor and air from entering. Extra security is built into the bag with no tear notches and 5 mm seams, creating the desired the tamper-resistant bag. Zero smell.
