The KUPA name is now synonymous with high-quality electric nail filing equipment. Kupa is devoted to producing quality products to nails salons everywhere. KUPA has implemented a four-point plan to develop several proprietary products: 1. Middle-Market Electric Nail File Machine. The MANIPro Original® was developed to be a middle-market product in the KUPA product line. It brings to manicure tables the basic features expected from a KUPA product without additional costs. Superior-Grade Carbide Bits. When the nail industry needed high-quality and competitively priced bits to use with electric nail files, KUPA initiated the use of Precision Carbide Bits. Many of the industry’s current carbide designs were developed by KUPA. 2. The Newest E-File. At present Kupa offers an extensive line of E-Files for every level of nail technician. The newest model is the Portable MANIPro Passport® with the “first ever Acetone Resistant Control Box”. Nail Professionals everywhere have spoken and have voted the MANIPro Passport® the #1 electric nail file for nail professionals by readers in both the Nails Magazine Readers Choice Awards and NailPro Magazine Awards. 3. Professional Enhancement Line. A complete collection of nail enhancement products – Artfinity (Nail Embellishments), Divinity (Acrylic Nail Extension Products), Gelfinity (Hard Gel Nail Extension Products) and Dipfinity (Dipping Products) are KUPA’s exciting newly created product lines. We aim to fill the void left by dealers that are not authorized retailers of Creative Nail Design or OPI products. 4. Our Website. Kupa has developed an extensive website featuring our E-files and Enhancement Products, as well as informative “how to” educational videos that can be viewed on Kupa TV through our YouTube channel free of charge. https://www.youtube.com/user/KupaInc KUPA will continue to create and launch proprietary products that meet the needs of nail technicians. Future products will incorporate technology from within and outside of the nail industry to make the nail technician’s life more convenient, portable, safe and cost-effective. Over the next few years, KUPA will also be developing electronic articles and guides to help nail technicians improve their business as well as their nail-filing skills.
