Coloured pencils are sometimes used by teachers or editors to correct submitted texts, but are typically regarded as art supplies, especially those with waxy core binders that tend to smear on paper instead of erasing.

In addition, the parties stated that the mixture produced through the addition of the catalyst to the resin component is destined only to be mixed with foundry sand and, ultimately, to be used as a foundry core binder.

Counsel submitted that the addition of Catalyst 3500 (Part III) to the phenolic resin component (Part I) creates a mixture which is specifically described in the Explanatory Notes to heading No. 38.23 as: foundry core binders based on ... polymers of Chapter 39, etc.

In response to the statement of the appellant's representative that the respondent's reference to the end product should not be read into the legislation, counsel for the respondent submitted that, once the catalyst is added to the resin component, the resulting goods are destined only to be mixed with foundry sand for use as a foundry core binder.
