Glass Tips 10mm Spiral Vortex Clear Filters - 50 Count Perc Tips

I use the 10m perc tips. I wouldn't reccomend going smaller personally. And bigger is better as it will not consentrate the smoke as much. https://a.co/d/0iTiPbgN this is a 50 pack but I bought a 10 and just toss them into a jar of iso after I use them and rinse them after I use 5 or so.
