Good morning Sir, I think around 250-350g with the liquid inside

That must be a big bottle of perfume.

If you plan on boxing them, you'd need to add weight (preferably using dry Ice) as close as possible to the original product.

EDIT: Good morning to you too.

Yep, these niche perfume bottles are hella heavy, I am planning on doing a tom ford 250ml bottle
