Review on Lab Bottle Funnel Set of 5 - Small Size: Ideal for Sand Art, Perfume, Spice, Powder, Essential Oil, Recreational Activities, Kitchen - BPA-Free Plastic, Food Grade by Brad Wall

Nothing to say here, this is a very simple product. All 5 funnels arrived intact, they look exactly like the photo on the product page and they work well enough to pour fine powders and liquids into small containers. My only minor complaint is that the funnel is quite narrow and the funnel's smooth, rounded shape tends to create a fairly tight seal, so I've used these funnels to spill thicker liquids like propylene glycol to pour into a small bottle . a few times - but this problem is easy to solve, just hold the funnel up and don't let it rest on the bottle and don't pour too fast. homemade juice bottles for e-cigarettes and supplements that I take in very small doses that are easiest to measure by volume. A friend of mine to whom I gave one uses it to fill his, um, essential oil burner tube with a crystalline compound, which he first pulverizes, and he says it made the process so much easier without adding anything to it spill, although sometimes not crushed enough. The pieces clogged him up and he had to use either a flattened paperclip or some similar "pumpkin thingy" to push them through. So if you're casting powdered crystalline material, be sure to grind it well first.
