- Item #: 2005
Great for giving your cultures lots of surface areas for the flies to move around on and allows more ventilation compared to coffee filters. Very finely shredded aspen excelsior. Enough for over 25 cultures at 0.3 ounces worth per culture. Our Aspen is not dyed and as such it is very light in weight.
