DUO Shape Forms - Coffin Andreia x 240

Andreia Duo Shape Forms Coffin x 240: the professional dual form system for clean, fast and perfectly structured nail extensions

The Andreia Duo Shape Forms Coffin x 240 are a professional solution designed for nail technicians, nail artists, educators and beauty professionals looking for a reliable, fast and elegant extension system. Thanks to their dual form system, made up of a base mold and an upper mold, these forms make it possible to create controlled extensions with outstanding precision while saving valuable treatment time. The Coffin shape, highly appreciated for its modern and sophisticated finish, instantly enhances the hand and works beautifully for both subtle sets and more statement nail designs.

Created to deliver uniform thickness, a balanced C-curve and an impeccable finish, Andreia Duo Shape Forms are perfectly suited to salon work as well as mobile appointments. Their transparent design improves visibility during application and gives better product control. The result is natural, fast and professional, with wear of up to 4 weeks depending on preparation, technique and client aftercare.

An innovative dual form system for more precise nail sets

What makes Duo Shape Forms - Coffin stand out is their smart two-part design. The base mold helps create a clean, stable structure, while the upper mold supports the shaping of the extension for a smooth, even architecture. This method simplifies the building process and helps achieve a consistent shape from the earliest stages of the service.

For professionals who want to improve speed without compromising quality, this system is an excellent choice. It reduces heavy refining after curing, makes it easier to visualise the desired length and helps prevent structural irregularities. It is especially useful for full salon sets, regular clients, premium express services or professionals who want more consistency across every set they create.

Why choose the Coffin shape?

The Coffin shape is loved for its balanced, feminine and highly on-trend silhouette. Its softly tapered profile with a straight free edge creates a chic, structured and visually elongating finish. It enhances the fingers, gives the hand a polished look and works equally well for an elegant nude set or for more creative nail art. With Andreia Duo Shape Forms Coffin, this iconic shape becomes easier to achieve consistently, even during a busy working day.

This format is especially suited to clients who love contemporary, refined and visually clean manicures. It also supports a wide range of nail art styles, including baby boomer, modern French, glass effects, encapsulated designs, glitter looks, minimalist nail art and bolder creative finishes. Thanks to the structure already guided by the form system, the result stays neat, controlled and professional.

Step-by-step guide: how to use Andreia Duo Shape Forms Coffin

Preparation

1. Select the correct size for each nail by choosing the form that best matches the natural width of the nail plate.
2. Prep the inside of the tip with a buffer or file on the matte area to improve adhesion of the building product.
3. Prepare the natural nail by removing all surface shine and cleansing carefully with a suitable product such as Prep + Clean.
4. Apply Primer and allow it to air dry for around 60 seconds.

Application

1. Apply a layer of product inside the tip on the previously prepared area. A builder product such as One Bottle Builder Gel Clear can be used for this step.
2. Position the tip correctly on the natural nail, making sure the structure is aligned and stable.
3. Cure under the appropriate lamp, such as a PRO EXTEND, to secure the form properly.
4. Repeat the process on the remaining nails while keeping visual control of length and placement.
5. Fully cure both hands under a professional lamp such as an A.Lamp Pro for complete polymerisation.
6. Remove surface shine with a 100/180 buffer to prep the tips for colour and finishing.

Colour and finishing

1. Apply a first coat of colour, such as gel polish, then cure.
2. Apply a second coat if needed to intensify the shade and even out the finish, then cure again.
3. Finish with a Top Coat and cure to protect the colour and add shine.
4. Remove the inhibition layer with a finishing product such as Extra Glow if required.

As a guide, curing can be carried out for 60 seconds under LED or 120 seconds under UV. The exact curing time may vary depending on the lamp model and wattage used.

Professional tips for an even better result

• Always check the size selection carefully before application, as a poorly fitted form can affect both adhesion and appearance.
• Follow a thorough natural nail prep to maximise wear.
• Use the guidelines to match the extension length easily from nail to nail.
• Work with a building product suited to your technique, pace and your client’s needs.
• Sanitise reusable forms thoroughly after each use to maintain a flawless hygiene protocol.
• Check the extension axis before curing to achieve an elegant, balanced set.

Maintenance and refill: a system designed for long-term client wear

One of the major advantages of Andreia Duo Shape Forms is the possibility of carrying out maintenance without completely removing the extension. This offers greater comfort for the client and more flexibility for the professional. During a refill, simply remove the top coat and colour, prep the regrowth area, even out the structure, then rebuild the necessary section with a suitable product such as builder gel or acrylic depending on your preferred technique.

This refill-friendly approach makes the system especially interesting for retaining regular clients. The set remains elegant, the regrowth can be corrected easily and the structure can be perfected at every appointment. It is a real advantage for clients who want to maintain beautiful length without starting from scratch each time.
