The first support member has a first eraser pad with a first surface area. The second support member is coupled to the first support member and has a second eraser pad with a second surface area that is different than the first surface area. The second support member is removable from the first support member such that the second eraser pad is usable independently of the first eraser pad. ## Claims ### Claim 1 An eraser assembly comprising: a first support member including a first eraser pad having a first surface area; and a second support member coupled to the first support member and including a second eraser pad having a second surface area that is different than the first surface area, the second support member being removable from the first support member such that the second eraser pad is usable independently of the first eraser pad; wherein the first support member and the second support member are usable together as a single eraser when the second support member is coupled to the first support member, wherein the second eraser pad is covered by the first support member when the first and second support members are coupled together as the single eraser, and wherein the first surface area of the first eraser pad is greater than the second surface area of the second eraser pad. ### Claim 2 (depends on 1) The eraser assembly of claim 1, wherein the second support member extends away from the first support member to form a grip of the single eraser. ### Claim 3 (depends on 1) The eraser assembly of claim 1, wherein the first support member defines a recess, and wherein a portion of the second support member is received in the recess to couple the second support member to the first support member. ### Claim 4 An eraser assembly comprising: a first support member including a first eraser pad having a first surface area; and a second support member coupled to the first support member and including a second eraser pad having a second surface area that is different than the first surface area, the second support member being removable from the first support member such that the second eraser pad is usable independently of the first eraser pad; wherein one of the first support member and the second support member includes a tab, and wherein the tab engages the other of the first support member and the second support member to releasably couple the second support member to the first support member. ### Claim 5 An eraser assembly comprising: a first support member including a first eraser pad and a recess; and a second support member including a second eraser pad, a portion of the second support member being removably received within the recess of the first support member to couple the second support member to the first support member; wherein one of the first support member and the second support member includes a tab, and wherein the tab engages the other of the first support member and the second support member to releasably couple the second support member to the first support member. ### Claim 6 (depends on 5) The eraser assembly of claim 5, wherein the first support member covers the second eraser pad when the portion of the second support member is received within the recess. ### Claim 7 (depends on 5) The eraser assembly of claim 5, wherein another portion of the second support member extends away from the first support member to form a grip. ### Claim 8 (depends on 5) The eraser assembly of claim 5, wherein the first support member includes a first generally planar surface and a second generally planar surface, wherein the first eraser pad is coupled to the first generally planar surface, and wherein the recess is formed in the second generally planar surface. ### Claim 9 (depends on 5) The eraser assembly of claim 5, wherein the tab is supported on a cantilevered portion of the second support member. ### Claim 10 (depends on 5) The eraser assembly of claim 5, wherein the second support member defines a storage area. ### Claim 11 (depends on 10) The eraser assembly of claim 10, further comprising a cover member removably coupled to the second support member, wherein the cover member provides selective access to the storage area. ### Claim 12 An eraser assembly comprising: a support member including a first eraser pad and having an outer perimeter; and a handle removably coupled to and extending away from the support member, the handle including a second eraser pad, the handle being positioned within the outer perimeter of the support member when coupled to the support member; wherein the support member has a length and a width, wherein the handle has a length and a width, and wherein the length and the width of the handle are smaller than the length and the width of the support member; wherein the first eraser pad has a first surface area, wherein the second eraser pad has a second surface area, and wherein the first surface area is greater than the second surface area. ### Claim 13 (depends on 12) The eraser assembly of claim 12, wherein the handle is removable from the support member such that the second eraser pad is usable independently of the first eraser pad. ### Claim 14 (depends on 13) The eraser assembly of claim 13, wherein the support member covers the second eraser pad when the handle is coupled to the support member. ### Claim 15 An eraser assembly comprising: a first support member including a first eraser pad having a first footprint area; and a second support member coupled to the first support member and including a second eraser pad having a second footprint area that is different than the first footprint area, the second support member being removable from the first support member such that the second eraser pad is usable independently of the first eraser pad. ### Claim 16 (depends on 15) The eraser assembly of claim 15, wherein the first eraser pad and the second eraser pad are generally rectangular. ### Claim 17 (depends on 15) The eraser assembly of claim 15, wherein the first support member and the second support member are usable together as a single eraser when the second support member is coupled to the first support member. ### Claim 18 (depends on 17) The eraser assembly of claim 17, wherein the second eraser pad is covered by the first support member when the first and second support members are coupled together as the single eraser. ### Claim 19 (depends on 18) The eraser assembly of claim 18, wherein the first footprint area of the first eraser pad is greater than the second footprint area of the second eraser pad. ### Claim 20 (depends on 15) The eraser assembly of claim 15, wherein one of the first support member and the second support member includes a tab, and wherein the tab engages the other of the first support member and the second support member to releasably couple the second support member to the first support member.
