Containers of cum, piss etc
I have acquired a lot of small (10g) plastic containers. I will fill them with any bodily fluid you can think of (cum, piss, saliva and sweat are the ones that come immediately to mind) and send them to you. These are fun-size, so discretion is guaranteed. Best of all, they are super cheap. At current exchange rates, they are under £10! Ideal for the man on a budget.
