## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10518:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE10518:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)

## Description

A specialised workpiece designed specifically for high-end laser engraving applications. Unlike standard drinkware that reveals a plain and kind of boring metalic finish when etched, this tumbler features a multi-layered coating that, when processed by a laser, reveals a vibrant iridescent pattern underneath the matte black exterior.

Makers often struggle with engraving large-capacity tumblers because the handles interfere with rotary attachments and laser head clearance. This unit eliminates that with a fully removable handle, allowing you to achieve seamless 360-degree patterning using a rotary tool without the mechanical obstructions common in off-the-shelf drinkware.

### Features

- **Create striking, multi-colour designs** with a specialised coating that reveals a brilliant iridescent effect upon laser contact, removing the need for post-process paint filling or vinyl.
- **Achieve full 360-degree engravings** with a detachable handle design that allows the tumbler to sit in rotary attachments, ensuring zero interference with the laser’s focal path or bed.
- **Save time and reduce material waste** by using pre-verified parameters from the xTool Material Easyset Library, providing a "plug-and-play" experience for both CO2 and diode laser users.
- **Provide versatile utility** with a tapered base designed to fit most Australian standard car cup holders, making it as practical as it is customisable.
- **Deliver a complete retail package** including a splash-resistant lid, two stainless steel straws, and a silicone tip, providing immediate value to your clients.
