We don't claim that all plastic is bad! Plastic is a good option if it is reused over and over and over again, then recycled at end of life. We like this empty refillable bottle because
a. You can see when it's almost time for a refill
b. unlike a mason jar sitting by your kitchen sink, this bottle won't break especially if you have little hands around
c. You won't cling clang walking down the street while carrying this bottle in your tote along with other bottles for RE filling at The RE Place.
