Qulkws 5280BCPA6061 fastener 12 pcs 30 mm 40 mm

Clear double-sided suction cups

This pack contains twelve transparent PVC suction cups in two diameters: six at 30 mm and six at 40 mm. The double-sided design grips two smooth surfaces at once, creating a consistent gap for glass shelves, mirrors, aquarium panels or lightweight décor. Each cup is made from flexible plastic that resists crushing and can be softened in warm water if it becomes misshapen. The clear finish stays discreet on furniture and fittings.

Suited for light spacing tasks

These cups work well for home and office jobs that need a small, reusable stand-off on glass, ceramic or polished metal. They can hold lightweight objects such as phones, string lights or small ornaments. Buyers who need to support heavier loads or mount items on porous or textured walls should consider larger or alternative fixings. The adhesive-free design also means they are not a permanent bonding solution.

Two diameters in one pack

The assortment provides 30 mm and 40 mm cups together, so you can match the cup size to the gap or load required. This mixed sizing is the key specification that determines whether the set fits your spacing or mounting needs. All cups share the same clear PVC construction and double-sided suction action.
