I don't even know where else to post this!
so, I want to post some bubble bath powder, basically the same as bath bombs but in powder form and some sugar scrubs. so I only need the size and weight of a small letter as it will be under 100g. BUT I think I will go slightly over when it comes to the depth as a small letter should only be 5mm in depth.
Whats my best option?!
I am utterly crap at postage!
