Same in Dutch: zeeëgel.

Yeah, I can relate to this…

Only if it’s a short ‘e’, if the pronunciation is long, you do use an apostrophe.

You would be right. I have the same packs. I don’t know if I bought old stock, but I bought the pack with the blue lid recently, the black lid pack is older.

The black lid pack contains bee wax and more water than the blue lid pack (64% vs 57% of the natural ingredients).
