Today I received these bottles. I might be wrong, but it seems as those are not PE. All the PE bottles that I have, from several other sources, are much softer.

These are much sturdier than I am used to find with PE, I expected softer bottles.

Anyways, don't know if I'll use them for e liquids. Think I'll await other people's findings.

It could be that you have only used LDPE & that these bottles are made from HDPE, both are PE but HDPE feels sturdier, just not as sturdy as PET.
