OG exemplary drawing
 
1. A dry multi-ply toilet tissue comprising:
1) A first ply comprising a layered, dispersible fibrous structure comprising:
a. a first exterior body contacting layer comprising 100% spun hydroxyl polymer fibrous elements by weight of the first exterior body contacting layer, wherein the first layer comprises a monoplanar surface; and
b. a second layer comprising a first web material comprising a first wet laid fibrous structure ply formed from an embryonic web material of wood pulp fibers and about 65% to about 75% water, comprising a three-dimensional (3D) patterned fibrous structure comprising 100% wood pulp fibers and exhibits temporary wet strength, wherein the second layer comprises a multi-planar surface relative to the monoplanar surface of the first layer;
wherein the spun hydroxyl polymer fibrous elements of the first layer are spun from a die and directly laid on top of and bonded to a surface of the 3D patterned fibrous structure and form a surface-deposited surface material on the surface of the 3D patterned fibrous structure; and wherein the surface-deposited surface material forms an exterior surface of the layered, dispersible fibrous structure; and
2) A second ply comprising a second wet laid fibrous structure ply;
wherein the dry multi-ply toilet tissue exhibits a Force Variability Value of less than 1.40 as measured according to the Glide on Skin Test Method;
wherein the dry multi-ply toilet tissue exhibits a Force to Drag Value of less than 100 as measured according to the Glide on Skin Test Method;
wherein the hydroxyl polymer fiber elements of the first ply first layer exhibit a length of 5.08 cm or greater and an average diameter less than 10 μm and the naturally occurring fibers of the first ply second layer exhibit a length of less than 5.08 cm and an average diameter greater than 12 μm;
wherein the dry multi-ply toilet tissue comprises an exterior surface that is void of surface chemistry agents.
