Our medium mystery box contains 3 to 4 different random swab sets, prints, and/or spore syringes from my available library. You never know what you may get, but I can say you will get hand selected spores that represents the best genetics of each variety. In short, only the best samples are collected here at Tastee Spores. Please note, the varieties shown in the photos are NOT what you will receive, only an example of what a Medium Mystery Box may look like. All samples are labeled for taxonomy and collected in laminar flow. All mystery boxes come with a detailed write up explaining what each variety in their box is and who is responsible for it. All spores are intended for microscopy purposes. We ship the same or very next business day, always USPS First Class. Mush love to all and to all, love mush.
