Part of my trade offering is the D. binata in a 50 mL centrifuge tube, in water. And now I wonder about the ethics of it when the people in the post office ask if what is being shipped is liquid, fragile, perishable, etc... It IS in liquid and it IS perishable. So can I really ship them... or aquatic utrics... or plants, in general?
What exactly is considered 'liquid' and/or 'perishable'? Should I justship my D. binatas in moist paper towels, instead?
