Where to buy plastic grade 5 fridge bottles?

As the titles says, I am looking for fridge bottles that are made from grade 5 plastic.

I only see grade 1 available in the market and even online. What's the use of grading when only one type of plastic is gonna be available everywhere?

I can't buy the glass bottles or even the steel ones because my daughter (14 months old) likes to sometimes grab everything that we have in our hand and I don't want her to bump the steel or glass bottle and hurt herself.


Get genuine Tupperware bottles. I have a few and they are all grade 5 marked. The quality is also really good and some have been in my possession for years and are still airtight.
