It worked as expected. The best part of the order was that I ordered this item around 3in the morning and it arrived later that afternoon around 3pm I believe. That's insanity! So very fast! Not the 1st time desertcart has pulled off this crazy stunt. Makes me kinda worry their employees aren't getting over worked.... Sure hope not. I bet it's just they have gotten so good at what they do now and hubs/warehouses all over. I live in Portland Oregon so pretty big city known for its Tech Savvy-ness and tech inclined residents so makes sense to have a warehouse near my local stocked with things to makes insanely quick delivery times like this... At least I HOPE that's the case hah. Anyways, totally awesome and totally good item. Review: Must have for bench jewelers - Borax cones used for flux in Jewelry making not really easy to find in the US normally found in Europe with high shipping costs. Very nice to have access to them in the United States. Has bench jewelers use this every day. ## Features - INSTRUCTIONS: Add A Couple Drops Of Distilled Water to Crucible, Start Grinding The Borax Cone In A Circular Motion Until The Water Turns To A Milky Paste Consistency and Now Your Ready To Use! - Used to Keep Metal Deoxidized During Melting. - EASY to Used & Melt. - Size: 4oz. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | RJS | | Part Number | 1 | | Item Weight | 4.6 ounces | | Package Dimensions | 5.83 x 4.61 x 3.5 inches | | Item model number | 1 | | Material | Other | | Item Package Quantity | 1 | | Batteries Included? | No | | Batteries Required? | No | ## Images ![Borax Flux Cone 4oz for Glazing Crucibles and Soldering - Image 1](https://m.media-amazon.com/images/I/51yibWlvqtL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Came within HOURS of ordering *by L***A on June 1, 2022* This is a smaller cone then I assumed it would be, these are known to last ages though so not concerned.
