Correction Fluid, Correction Roller
Correction tape is an alternative to correction fluid used to correct mistakes during typing, or, in some forms, handwriting. One side of the tape, which is placed against the area to cover, is coated in a white, opaque masking material. Pressure applied to the other side of the tape transfers this material to the paper. Unlike correction fluid, the covered area can be written on it immediately after applying. As it is solid, correction tape is not subject to misuse as an inhalant, unlike most correction fluids.
A correction fluid or white-out is an opaque, usually white, fluid applied to paper to mask errors in text. Once dried, it can be written over. It is typically packaged in small transparent bottles, and the lid has an attached brush (or a triangular piece of foam) that dips into the bottle. The brush is used to apply the fluid onto the paper. It can be used for many purposes.
