I don't think I can answer your questions upon the shipping of cactus soils or the mushie kits....but I will say that I do know that the actual syringe (being the dispensing device) is not allowed to be sent to Canada....I settled for just spores(which came with a customs label "garden seeds") and would have to say they made it to N.B. Canada no problem. Everything I requested came and I am 90% satisfied with what I recieved (the other 10% has to do with one print out of them all, which doesn't seem too feasible to use! But I know that is just a fluke most likely!) As for the other prints....A+++!!!
