Decorating sets use water-based ink and polish without phthalates and formaldehyde. Recent releases of nail art kits from China highlight nontoxic materials and odorless components. The latter is emphasized because a sharp scent is indicative of noxious chemical ingredients. Fragrances that can mask the smell are considered allergens. Suppliers of artificial nails utilize safe ABS and acrylic instead of PVC, which may contain hazardous lead. These are decorated with water-based acrylic and gouache paint. Stamping and stencil sets feature nail polish that does not incorporate harmful substances such as DBP, acetone and formaldehyde. Further, the lacquer is not flammable and has no aroma. The adhesive for stickers and other ornaments boasts a neutral odor as well. Makers send samples to third-party testing institutes such as SGS to obtain certification that products contain allowable levels of regulated elements such as heavy metal and phthalates. Although not marketed as toys, releases are evaluated against EN 71 requirements to demonstrate safety for all users, even young ones. Among the various kinds of nail art kits from China, 3D stick-on ornaments are gaining popularity. Models made of ceramic and resin come in flower and butterfly contours. Polymer clay strips that yield custom shapes are also available. Other types of embellishments include rhinestones, feathers, dried flowers, faux pearls, paillettes and wire. Nail stickers are produced by silk-screening or offset-printing foam ink onto a PET base with adhesive backing. Glitter and rhinestones can be added as well. Designs are sold in sheets, priced at $1 to $3. Those shaped like fingernails have 10 pieces on each leaf, while smaller styles are grouped in larger numbers. Acrylic and ABS nails are normally packed 24 pieces to a box, but sets of 12 are offered as well. They may have a preapplied coating of glue. Several versions must be attached by putting professional TRE adhesive with a nail brush. Such tools are offered in sets or individually. Adopting small tips, they are also suitable for painting intricate motifs. The bristles are made of nylon, kolinsky or sable, while the ferrules are in aluminum or copper. Acrylic, resin and wood are the handle options. Prices start at $0.15 for one piece and can reach $4 for a set of 12. Animal-hair models are about 30 percent more expensive than designs employing synthetic fibers. Stamping systems consist of a stainless steel plate with seven or eight engraved patterns, a bottle of nail polish, a stamper and a scraper. The lacquer is dabbed onto an image and then the excess is removed. The stamper lifts the figure from the plate and transfers it to the nail. Professional stencil sets include templates, paint and an airbrush. The guides are also available separately and may be used with regular nail polish. UV gel kits comprise the colloidal preparation and a curing lamp. Thin but strong artificial nails are molded and then dried for two or three minutes. Stamping, stencil and UV suites generally come with visual instructions, some of which are in DVD format. Nail art printers apply digital motifs onto 10 nails simultaneously. A few models can also be used on other objects such as mobile phones. New designs may be uploaded by connecting to a computer.
