NOTPOLISH INC is a nail-product manufacturer and wholesale distributor headquartered at 4620 Alvarado Canyon Rd Suite 2 in Grantville, San Diego 92120, founded in 2018 and operating with approximately 40 employees. The Alvarado Canyon address sits in Grantville's light-industrial corridor near the SDSU Transit Center, housing both the company's production facility and its showroom where nail technicians can browse inventory in person. The product catalog spans acrylic nail powders, gel polish collections, dipping solutions, EMA liquid monomer, builder gels, and the company's proprietary Solo Gel line — a TPO-free and HEMA-free formula designed for both UV and LED curing across 48 color options. Grantville's Nail Origins on Mission Gorge Rd runs the kind of high-volume station work that demands the bulk acrylic and monomer supply NOTPOLISH distributes from its Alvarado Canyon warehouse. Reflective glitters, glow-in-the-dark pigments, and nail art accessories fill out the specialty segment, and the company emphasizes that key formulas are made in the USA. Starter kits bundle acrylic powder, monomer, brush, nail tips, and prep tools into single-purchase sets aimed at cosmetology students and newly certified nail technicians entering the San Diego market. The company ships nationally with no-cost shipping on orders above $75 and maintains a Shopify-based e-commerce platform alongside the walk-in showroom. The 92120 corridor along Alvarado Canyon Rd runs Grantville's manufacturing and distribution businesses parallel to the consumer-facing personal-care strip, and NOTPOLISH anchors the wholesale supply side that feeds San Diego's salon economy through the same commercial zone where Unique Threading operates its retail brow-and-threading service. The Solo Gel round-tip precision brush hugs nail curvature during application, reducing flooding at the cuticle line and sidewall — a design detail that separates the formula from flat-brush competitors in the nail-tech gel market.
