Weight approximately 13.9 oz each.
These are cores from industrial stretch wrap. Uses may include shipping, used for speaker ports, storage for gun scopes, and multiple craft applications.
P.S:
(I also sell 3" badger core plugs that fit perfectly onto these with a little hot glue attached for nice end caps!)
NOTE: Seller reserves the right to select the least cost shipping option, as orders of more than one are subject to Dimensional Weight calculation. eBay does only double the weight of an item and not the dimensions.
