To comply with postal regulations we have to ship the jars without fluid, but you just need to refill them with 70% isopropyl alcohol. It's available and inexpensive at Shoppers Drug Mart or any pharmacy.
For size reference, these jars are roughly ~2.5" tall. PRICE IS PER SPECIMEN.
We refuse to use formaldehyde, due to the high risk of nerve damage and cancer from exposure. We feel it is extremely irresponsible for sellers to put their lives and the lives of their customers at risk for a decorative object.
