## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE11097:1` (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/CE11097:1.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.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Suspend a three-dimensional scene inside solid glass. This 80 mm sphere of high-clarity K9 optical crystal is made for UV laser inner engraving, turning photos, pets, landmarks and 3D models into floating keepsakes that glow when lit from below.

Not all glass engraves cleanly. Ordinary soda-lime glass carries a green tint and trapped bubbles that scatter the laser and cause unwanted cracking. K9 is closer to optical-component grade: crystal-clear, virtually bubble-free and consistent between every blank. Every micro-fracture the laser places lands crisp and exactly where you intend it.

Spheres act like a lens, so xTool's workflow submerges the ball in refractive-index-matched inner engraving oil and holds it centred in a fixture ([sold sperately,](https://core-electronics.com.au/xtool-k9-crystal-ball-inner-engraving-kit-f2-ultra-uv.html) this is a standalone blank). xTool Studio includes a dedicated K9 Crystal Ball preset, and the supplied material QR code loads tested processing parameters for you. There is no trial-and-error before your first engrave.

### Features

- Designs appear suspended inside the glass with the surface untouched, thanks to subsurface UV laser engraving.
- Crisp, distortion-free detail, courtesy of high-purity K9 optical glass with no green tint and virtually no bubbles.
- Fewer wasted blanks: xTool's K9 is tuned and parameter-tested for its UV lasers, reducing the risk of cracking.
- Fast setup via the material QR code and the built-in K9 Crystal Ball preset in xTool Studio.
- Sized to suit xTool's official Crystal Ball Inner Engraving Fixture and glass cup, for repeatable positioning and correct oil volume.
- Versatile processing: supports UV inner engraving, surface engraving and embossing on the xTool F2 Ultra UV.
- A standout personalised gift for weddings, anniversaries, memorials, pet tributes, awards and festive décor. Pair it with an LED display stand to make the engraving pop.
