Alibaba K9 Crystal Test – Day 5 FAIL (0 for 5 So Far)

This is Day 5 of my daily K9 crystal testing series. Supplier: Alibaba Seller: Pujiang Daoshen Arts & Crafts Co., Ltd. Crystal Size: 40 × 40 × 60 mm Laser: xTool F2 Ultra UV Test Method: Same inner engraving workflow Same laser Same settings Same placement Same file Result: ❌ No visible inner engraving That makes this 0 for 5 so far. These crystals pass a basic UV light test but consistently fail when it comes to actual inner engraving, which is what matters if you’re buying K9 crystals for UV laser work. I’m documenting one crystal per day so other makers can see repeatable results before spending money. If you’re researching K9 crystals for: UV inner engraving xTool F2 Ultra UV Cockpit3D or similar workflows Watch this series before you buy. 👍 Like if this helps 💬 Comment if you’ve seen similar results 📌 More tests coming
