Hotfix flat-back MC glass crystals, SS20 (Ø 4.6–4.8 mm) | Rhinestones, Swarovski etc

High-quality hotfix MC glass crystals offering enhanced brilliance and more reflective facets compared with standard low-cost crystals. Precision cutting creates a brighter sparkle and a refined finish.

Effects:
The AB (Aurea Borealis) finish creates a multi-colour reflective effect.

Metal-coated crystals are opaque.

Volcano changes appearance depending on viewing angle.

Opal crystals have a soft milky opaque finish.

Application

For faster and more precise application, we recommend using an applicator.

The applicator heats only the crystal and allows accurate placement.

KL24 recommends

For best durability, use a gel-type instant adhesive.

Bostik gel adhesive has proven especially effective.

When applying with an iron:

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

Always test on a sample piece before full application.
