Nelyrho 4 Pieces 1kg Graphite Ingot Molds for Casting Gold Silver Aluminum Copper Brass, Metal Melting Refining Tools (4.01 x 2.01 x 1.01 Inch)

Works fine

Awesome

My son melts metal. He loves this size. Its easily stored. This is the 2nd set ive purchased. He uses both sets. The 2 sets gives the first set a chance to cool a bit before he starts filling the 2nd set.

These work great. They are pretty sturdy as well

This is the correct size for the smelter that I use.

Great quality and fast Shipping

Worked

Thickness of the mold walls started shrinking after three to four uses. Updated one star to four stars. Exceptional customer service response. Replaced the molds with no fuss. The missing 5th star is for the original failure of the molds; otherwise, it would be a 5 star rating for customer service alone.

I've used them and they create perfect ingots and release easily
