The 21g(3/4 oz) size, dubbed the Pocket CA is available with Insta-Cure, Insta-Cure+, Maxi-Cure and Super-Gold CA's. It features a slightly different top that is designed more for use in the field. The top incorporates an internal pin so that when screwed in place the bottle is sealed meaning no loss when rattling around in a toolbox. To facilitate the pin the top of the bottle is a little thicker than a standard top making application of small amounts of CA difficult, but the addition of the extender tip solves this problem.
