With the xTool K5 Crystal Keychains, you can turn personalized UV engravings into small, illuminated gifts and promotional items. The set contains 10 heart shaped keychains made from transparent K5 crystal glass, each measuring 3 x 3 cm (1.18 x 1.18 in). The combination of high-quality crystal, precise engraving, and integrated multicolor LED lighting creates a particularly striking effect.
Engravings That Come to Life in the Light
The engraving appears white on the transparent crystal and can be illuminated in different colors by rotating the ring above the crystal. This changes the appearance of the design depending on the selected color, turning the keychain into a real eye-catcher.
The transparent K5 crystal glass features a smooth surface and high clarity. This ensures that even the finest and most detailed designs are showcased beautifully.
For Personalized Projects and Small Series
The keychains were specifically developed for processing with the xTool F2 Ultra UV, but can also be printed with a UV printer, for example.
Whether it is a name, logo, symbol, small image, or custom design, the compact format makes these keychains ideal for personalized gifts, keepsakes, club merchandise, or small promotional items.
With 10 pieces per pack, the set is also well suited for projects requiring multiple identical or individually customized keychains.
Replaceable Battery
The integrated LED is powered by a replaceable button cell battery, which can be replaced by the user when needed.

The Makeblock success story began in 2012 when Jasen Wang, the founder and CEO, had a groundbreaking idea. As a passionate maker, Jasen realised how difficult it can be to turn a creative idea into reality. This drive gave rise to his first project: Makeblock.
Makeblock specialises in promoting STEAM education. The company helps young students develop their creativity by developing educational infrastructure - including robotics modules, coding software and laser cutters. The aim is to give pupils the tools to learn technical knowledge and creative skills through play.
At the end of 2020, Makeblock expanded its portfolio and entered the field of laser machines. With the xTool project, the product range was expanded so that not only students but also adults can benefit from the solutions. Creativity is not just about developing programming robots - it is also about personalising everyday objects, such as engraving names on mugs or creating works of art from wood.
With the launch of the first product, the xTool D1 in 2021, Jasen started a new chapter in his vision. While the Makeblock success story continues, xTool marks the start of an exciting new episode.
