Hold on is it plastic?
The ends contain TPE - an environmental friendly over-moulding material, the rod is nylon, the case is made from a fully biodegradable corn-based material that is compostable and the box is recyclable, unbleached paper.
Durability is the key, for one object to do the job of 1000's disposable buds used per person each year.
If it were to end up in the ocean (which if you dispose of correctly it wont), it's damage is less than 0.1% of the single-use alternative, simply because there will be much less of them, 999 less.
So in the grand scheme of things, it is better for the environment!
