NASAL FILTER BOX.

Description

You buy the filters and they don't even give you a box so they don't get dirty, another model that arises from necessity. Call me paranoid, but instead of the mask I use nose filters (the hole is for the larger filters, in case you are a big nose hee hee hee hee), when I enter a closed place I put them on, but they are also useful for earplugs, contact lenses, mini headphones.Creality K1 Max, which is the best, quality 0.8, 100% filling, only support on the printing plate, (see attached photos), has not done that part well without support.
