HERMA Warning Birds Window Stickers, 6 Realistic Bird Motifs on a 30 x 30 cm Sheet, Weatherproof Removable Film

The HERMA 15539 Warning Birds are self-adhesive window stickers — one 30 x 30 cm sheet with six different realistic bird motifs on strong weatherproof film — made to help protect glass doors, windows and conservatory panes from bird collisions in homes, offices and schools.

Birds often do not see clear or reflective glass as an obstacle. HERMA prints the motifs in colour on one side and in rich black on the reverse, which faces outdoors: the strong contrast is meant to help birds see the barrier. The stickers can be removed without residue and repositioned, so you can move them until they sit where they are needed.

• 1 x HERMA sheet 30 x 30 cm with 6 different self-adhesive bird motifs (article 15539)

• Stick the birds on glass that birds hit — patio doors, large windows, glass balustrades or conservatory panes.
• The colourful side faces into the room, the black reverse faces outside, so the decoration looks natural from indoors while giving birds a high-contrast silhouette.
• Self-adhesive and removable without residue: you can reposition a bird if it ends up in the wrong place, and take them off when you replace or clean the glass.
• Weatherproof film, so the stickers keep their look in sun and rain.

• It is not a static-cling sticker — the birds are self-adhesive, so they need clean, dry, smooth glass to stick well.
• Six birds will not protect a whole glass façade: coverage depends on how many you place, and HERMA does not publish a recommended spacing.
• They are not suitable for textured, frosted or dusty surfaces, where self-adhesive film does not bond properly.
• This is not a children's sticker set for paper or notebooks — it is film made for glass.
