A tactile stimulation system includes a writing utensil that may be manipulated thereby facilitating the writing utensil to write. A plurality of blocks is provided. The blocks are movably coupled together and the plurality of blocks may be manipulated. The writing utensil is coupled to the plurality of blocks. Thus, the plurality of blocks facilitates tactile stimulation when the writing utensil is manipulated.

A retractable pen including a first barrel, an ink cartridge, a second barrel, a clamping component and a spring; a main body of the ink cartridge, the spring and the clamping component are all located inside the first barrel and the second barrel, the spring is wound on a portion, close to the nib, of the ink cartridge, and the nib in a portion of the ink cartridge can be extended and exposed out of the first barrel; a mounting portion, muff-coupled to the first barrel, is arranged on the clamping component, and the clamping component is rotatable with respect to the first barrel; when the first barrel is muff-coupled to the second barrel, a polygonal neck is formed on a surface where an outer surface of the clamping component comes into contact with the second barrel.

A flexible marker includes a flexible body for gripping, and a marking implement carried at least partially within the body. The body is flexible to conform to the grip preferences of a user. The body has two parallel lateral sides and a first longitudinal end defining a central apex from which the marking implement can be extended. The body can be folded along or near a central longitudinal axis to bring together two lateral sides. The body can be folded along a first laterally extending axis in a first configuration in which the marking implement extends longitudinally beyond a second longitudinal end for use of the marking implement. The body can be folded along a second laterally extending axis in a second configuration in which the second longitudinal end extends longitudinally beyond the marking implement.

An improved hand held pen holding sleeve comprising a rigid barrel with a through bore abutting a deformable finger grip element also with a through bore. The pen holding sleeve is devoid of an ink reservoir or ink cartridge. The through bore of the pen holding sleeve is sized and configured to accept disposable stick pens and common pencils as the refill element. The deformable finger grip element is removable from the rigid barrel. The deformable finger grip element, formed of an elastomer, is the sole means for capturing and retaining the refill element within the pen holding sleeve.
