What is Jamberry? Jams are heat-activated vinyl nails wraps. They are unlike anything else you can buy anywhere else. They are not polish strips. They outlast the dollar store brands and even the expensive salon brands. They don't chip, fade, or smell -- and they don't dry out or expire. Jamberry nail wraps last up to 2 weeks on your fingers and up to 6 weeks on your toes. (YES!! You read that right!) At just $15 per sheet, you get an amazing value!!!
