The page lists Chaun Legend acrylic powders, from A401 LGND Signature Color, A402 Clear and the A404 Light Pink, A405 Medium Pink and A406 Dark Pink to coloured powders such as A129 Runway and A157 Berry Bloom, plus LGND 100% Kolinsky acrylic brushes in sizes #14, #16 and #18. Each powder is a separate listing with its own stock.
Prep the nail, push back the cuticle, remove the shine and dehydrate, then apply a primer suited to your prep. Dip the brush in liquid monomer, press out the excess, pick up a bead and place it, then press and shape it while it is workable. Keep product off the skin. Acrylic sets in the air without a lamp.
Clean the brush in the same liquid monomer you work with, never in acetone, which dries natural hair. Wipe it on a lint-free towel between beads, reshape the tip and store it lying flat or with the hair pointing down and covered. A well-kept Kolinsky brush holds a fine point for detailed work and a clean bead for structure.
Use a liquid monomer from the same brand as the powder whenever you can, because each brand tunes its liquid to its powder for set speed and working time. If you have to mix brands, test on a practice tip first, since the bead can set faster or slower than you expect and change how much time you have to shape.
Clear powder is for structure you want to see through and for encapsulated designs. The pinks, from light to dark, cover the nail bed for natural-looking sets and pink and white work. Colour powders give a finished colour without a gel coat. Most techs keep one clear, one or two pinks and a white, then add colours. Keep a dappen dish for each liquid so colours do not mix.
