Economy Core Flask Kit

Similar to our very popular Mini Core Flask kit but with some 1st generation resin parts in place of the 2nd generation filament parts.

* If resin parts are dropped they may break and we don't have replacements.

* Core colors may vary in color.

* This flask design is the older version and does not have the vent channels. Flask and other parts manufactured in-house here in Tucson Arizona.

* Inserts have one set of master tabs that work with all finger size cores.

* Comes with Core sizes 5 - 14 along with a resin bottom square for proper 1/2 round setup of the Core and Resin Core Blocks. Color is gray.

* Cores and end tabs are specifically designed to work with this flask design only.
