A sample storage assembly for storing a plurality of sample packets includes a sheet that is positionable in a three ring binder for storing the sheet. A plurality of pockets is each coupled to the sheet to insertably receive a sample packet. Each of the pockets is expandable or collapsible to contain a varying number of the sample packets. A plurality of elastomeric bands is each coupled to the sheet. Each of the elastomeric bands is aligned with respective ones of the pockets. Each of the sample packets is extendable beneath a respective one of the elastomeric bands. In this way each of the elastomeric bands inhibits the sample packets from falling out of the pockets.
