Specialist Fast Setting Plaster bandage 4 inch x 5 yard roll is ideal for creating field or lab casts to protect fragile fossils for transport or during preparation. We’ve found Specialist bandages to be the best quality we’ve worked with. They work exceptionally well for creating field casts to protect fragile bones during transport. We also use them occasionally in the prep lab. The work time is perfect – slow enough to allow time to work with it, but fast enough to be efficient.
