About this sign

The Twenty One LED Neon Sign writes the milestone in full across two lines of flowing script. Twenty sweeps across the top, while One sits beneath with a large rounded opening stroke. The connected lettering gives the design a handwritten appearance, making the shape of the words an important part of the celebration theme.

Display it at a twenty-first birthday above a party table, within a photo backdrop or on a clear wall near the gathering space. The long script strokes extend beyond the centre of the phrase, so include them when measuring for a listed size. Colour options are shown on this page to complement the surrounding décor. A quieter background helps the finer letter connections remain visible. The supplied remote and dimmer let you adjust brightness. Leave open space around both lines rather than crowding the design with other text, allowing the complete written milestone to serve as the main decorative feature.

Good to know

In the box: Your sign on a clear acrylic backboard, a 1.5 m clear cord with a power adapter and the plug for your country, the remote & dimmer, and your chosen mounting kit. Electrical approvals are issued against the power-supply model fitted to your sign — ask us and we will confirm them in writing.
Delivery: Free standard delivery. Allow 7–14 days from order to arrival — that includes making your sign. Couriered with signature on delivery.
Indoor or outdoor: Every design can be built either way and looks the same. Indoor is for dry indoor spaces. Choose Outdoor above for anywhere rained on, splashed or permanently humid: it swaps in outdoor-grade neon flex, a waterproof dimmer and an outdoor power supply sized to the sign. The IP67 rating applies to the neon flex, not the whole sign or its plug — ask us and we will confirm the rating for your build in writing.
Warranty: 24-month manufacturer warranty on electrical components when the sign is used as intended. An indoor sign used outdoors or somewhere wet is not covered.
Mounting: Backboards come pre-drilled. The wall mounting kit is free in silver, with black or gold finishes available above; a hanging wire kit or 3M tape can be added too.
Light & power: LED neon flex — lighter and tougher than glass, low energy, rated for 50,000+ hours.
Size & colour: Choose your width and the height follows this design’s proportions. 11 colours to choose from.
