Mini Core Flask Kit

A very popular kit. Wait times will vary depending on when you buy but I’m working daily to get these built and shipped.
* Core colors and square colors may vary from black to gray to blue.
* A brand new flask design with vent channels made specifically for sand casting more intricate ring patterns. Flask and other parts manufactured in-house here in Tucson Arizona.

* Cores have one set of master tabs that work with all finger sizes.

* Comes with core sizes 5 - 14 along with the bottom square for proper 1/2 round setup of the core. Color may be gray or black or blue.

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

Shipping: USPS priority Medium box.
