Available special-effect materials include glitter iron-on and glow-in-the-dark iron-on. Glow-in-the-dark materials should be "charged" in direct light for the best glow. Glitter iron-on gives a shimmer finish and is noted for holding up through multiple washes. For longevity, follow the product care guidance for iron-on materials (allow proper curing time and follow washing instructions).
Most listings identify PET (polyethylene terephthalate) as the primary material for vinyl and sticker sheets. Some sampler packs or printable sticker sheets may also include paper components.
Allow 24 hours after application before washing. Wash and tumble dry garments inside out, do not use bleach, and if you must iron, do so on the garment’s backside only. These steps help preserve iron-on adhesion and appearance.
