It is available in the big rolls shown above in a couple of thicknesses, but more recently it has become available in small sized rolls in building supply, hardware, and some drug stores.
Some applications:
To hold small plex labels (letter sized paper or smaller) - 3 or four small pieces (1/4" x 1/4") will secure the label. The use of small pieces like this also allows for easy removal of the labels from painted wall surfaces usually without damage. Remove the label with a twisting motion. tape that remains on the wall can be "rolled off" leaving no visible residue on the paint surface.
Using large amounts of tape especially metal to metal can be considered a virtually permanent bond.

#4910 Clear 0.040 (1.0) This family of clear tapes is excellent for applications where clear or colorless is desired. The general purpose
adhesive on both sides is suitable for high surface energy substrates.
Product Description:
3M™VHB™Tapes provide the convenience and simplicity of a tape fastener and are ideal for use in many interior and
exterior bonding applications. In many situations, they can replace rivets, spot welds, liquid adhesives and other permanent
fasteners.
These 3M™VHB™Tapes are made with acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing
and stress relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides
outstanding durability performance.
These tapes utilize a variety of specific foam, adhesive, color and release liner types to provide each product/family with
specific features. These features can include adhesion to specific or a broad range of materials, conformability, high tensile
strength, high shear and peel adhesion, resistance to plasticizer migration, and UL746C recognition. All 3M™VHB™Tapes
have excellent durability and excellent solvent and moisture resistance.
Note: All3M™VHB™Tapes should be thoroughly evaluated by the end user under actual use conditions with intended
substrates to determine whether a specific tape is fit for a particular purpose and suitable for user’s method of application,
especially if expected use involves extreme environmental conditions or high dead load stress.
