Water Pak...Ryan....
Sound like you are making something similar to what I purchase for about 22 cents US each....
Water Pak....chunk of foam, sealed in plastic, in a box with a cut-out on one side...same size as a rose box, and can be stapled in one end of the box....
We either use these, or tube all "loose" flowers....
Had a complaint just yesterday, sent the driver back to pick up the flowers, that "wilted" over night... driver gets there, pulls them outa the vase, and brings em back...
They were in a vase, of water, all right....WITH the tubes still on....DUH
