Hotfix flat-back Swarovski glass crystals, SS10 (Ø 2.8–2.9 mm) | Rhinestones, Swarovski etc

Glass crystals from one of the world’s most renowned crystal manufacturers. Their exceptional brilliance comes from premium materials, patented Xilion Rose cutting technology (up to 50% more reflective facets than standard crystals), and an advanced facet arrangement that creates vivid sparkle and a precision-polished surface.

Effects:
The “AB” marking after the crystal colour indicates a special surface treatment (Aurea Borealis). AB crystals create a multi-colour reflective effect in addition to the base colour. Their shine is softer than clear crystals but offers richer tonal variation.

Metal-coated crystals are opaque. This category includes: Aurum, Labrador, Jet Hematite, Silver Flare, Metallic Light Gold, etc.

Volcano is a special crystal finish that changes colour depending on the viewing angle — appearing violet, yellow, green, or orange.

Opal crystals are opaque with a soft milky appearance.

Application

SS10 crystals can be attached using an iron. For faster, safer, and more precise application, we recommend using an applicator.

The applicator heats only the crystal, not the base material, allowing more accurate placement. On harder materials (such as phone cases, notebooks, etc.), crystals can also be attached using an applicator or glue.

KL24 recommends:

For best durability, use the correct adhesive. We recommend a gel-type instant adhesive.

Bostik gel adhesive has proven especially effective — it does not drip, dries at a controlled speed, and creates a flexible bond between the crystal and surface.

Suitable for both hotfix and glue-on crystals.

When applying with an iron:

Crystals may shift during application.
Fabric may not tolerate the heat required for attachment.
Delicate materials may be ironed from the reverse side.

For best results, always test on a sample piece before full application.
