Cunno Round Adhesive Bicycle Reflectors — 16‑Pack (8 Red/8 Amber), 3in PMMA/ABS Weather‑Resistant Visibility

Cunno 16-piece round adhesive reflectors are stick-on safety markers made from PMMA and ABS that attach to bikes, helmets, vehicles, and gear to improve nighttime visibility.

These self-adhesive reflectors come in a pack of 16 (eight red, eight amber), each about 8 cm (3 inches) across, and are designed to be a quick, removable way to add retroreflective visibility to many surfaces. Their construction combines PMMA optical material and a sturdy ABS backing with an adhesive layer so they hold firmly but can be removed with minimal residue. They’re useful for cyclists, commuters, vehicle owners, and anyone who wants a simple, low-cost way to increase conspicuity after dark.

How do these reflectors attach and stay in place?

The reflectors use a pressure-sensitive adhesive on the back for tool-free installation. For best adhesion, clean and dry the mounting surface before pressing a reflector firmly into place; the packaging recommends wiping target areas first to improve cling.

• Pressure-sensitive adhesive backing for immediate stuck-on bond
• Works on smooth, painted, or hard plastic surfaces
• Wipe surface first to remove dust, oil, or moisture
• Removes later with minimal glue residue when peeled off

Will these reflectors survive outdoor use and rough conditions?

Built from PMMA for the reflective face and ABS for the structure, the reflectors are made to be compact and reasonably durable. They are sealed and rigid, resisting deformation during everyday outdoor use, but extreme impacts or prolonged submersion could shorten their service life.

• PMMA optical face for bright reflection
• ABS housing for shape retention and strength
• Sealed edges to reduce ingress of dirt and moisture
• Intended for general outdoor and road conditions, not heavy-impact environments

What are the practical uses and where should I stick them?

These round reflectors are versatile and designed to be applied anywhere added reflectivity helps: bicycle frames, helmets, trailers, hard hats, scooters, cars, kayaks, and more. Use them on rear and side areas to make movements more noticeable to motorists and pedestrians at night.

• On bicycles: seat tube, rear rack, forks, or helmet
• On vehicles: bumpers, trailer sides, RVs, and pickup beds
• On personal gear: helmets, hard hats, backpacks, and scooters
• On watercraft: boats and kayaks where visibility to light sources matters

How many reflectors are included and what are the color options?

The pack provides 16 round reflectors total: eight red and eight amber, each about 8 cm (3 inches) across. Having multiple pieces lets you cover several mounting points or replace lost/damaged reflectors without buying more.

• 16 reflectors per pack: 8 red + 8 amber
• Approximately 8 cm / 3 inches diameter each
• Enough quantity for multiple vehicles or gear sets
• Colors chosen to match common visibility conventions (rear/side markers)

Who is this for: The Cunno round adhesive reflectors suit commuters, cyclists, fleet owners, outdoor enthusiasts, and families who want a simple, low-cost way to boost night visibility across bikes, helmets, trailers, and small vehicles. They’re a practical accessory for anyone wanting quick installation, removable adhesion, and a set of multiple markers to spread across equipment or vehicles.
