The fibrous core of claim 1, wherein the fluted layer comprises a plurality of flutes having a wave-form shape. 8. The fibrous core of claim 7, wherein the plurality of flutes comprise at least one peak and at least one valley, and wherein an adhesive is disposed on the at least one peak, and wherein a rolled sheet product contacts the at least one peak to removably adhere to the fibrous core. 9. The fibrous core of claim 1, wherein the fluted layer comprises a plurality of flutes each having a flute axis, wherein the flute axis is at an angle to the longitudinal core axis of the fibrous core and wherein the angle of the flute axis to the longitudinal core axis is from about 0 degrees to about 90 degrees. 10. The fibrous core of claim 1, wherein the fibrous core further comprises a first open end and a second open end, wherein the first open end is opposite the second open end, and wherein the first open end and second open end defines a length therebetween, wherein the length is between about 2.5 inches and about 12 inches. 11. The fibrous core of claim 1, wherein the fluted layer comprises a plurality of flutes each having a flute axis, wherein the flute axis is substantially perpendicular to the strip axis. 12. The fibrous core of claim 1, wherein the fibrous core comprises an adhesive disposed on the outer surface. 13. The fibrous core of claim 1, wherein the fibrous core comprises an adhesive, and wherein the adhesive substantially covers the seam. 14. The fibrous core of claim 1, wherein the fibrous core comprises an adhesive, wherein the adhesive extends from the leading edge of the overlap portion to removably bind a rolled sheet product to the fibrous core. 15. The fibrous core of claim 1, wherein the fibrous core comprises a rolled sheet product rolled about the outer surface of the fibrous core. 16. The fibrous core of claim 1, wherein the fibrous core comprises a scent composition. 17. The fibrous core of claim 1, wherein the fluted layer is an outer surface of the fibrous core. 18. A fibrous core, comprising: an outer surface comprising a fluted layer; andan inner surface comprising a liner, wherein the liner is disposed on the fluted layer, and wherein the fluted layer and the liner overlap to form an overlap portion and a seam,an adhesive disposed on the overlap portion; andone or more indicia disposed on at least one of the fluted layer and the liner;and wherein the basis weight of the liner is substantially equal to the basis weight of the fluted layer, and wherein the fluted layer and the liner are in the form of a strip, wherein the strip comprises a leading edge, a trailing edge opposite the leading edge, and a strip axis substantially parallel to at least one of the leading edge and the trailing edge, and wherein the leading edge overlaps the trailing edge to form the overlap portion and the seam on the outer surface of the fibrous core and further wherein the strip comprises at least one compressed portion having a width measured from at least one of a first edge and a second edge toward the strip axis, wherein the plurality of flutes in the at least one compressed portion are compressed.
