Emjoi Divine Crystal Epilator (Aqua) AP-17KB/ Hair remover This Emjoi unit incorporates our NEW state-of-the-art Crystal Technology, representing a remarkable breakthrough in the science of epilation. These units also feature patented skin-glide technology and silver-ion technology – for a superior epilation experience. Why does Crystal Technology make a difference? Why is it better than other models offered by other manufacturers? Length – When you look at traditional epilators, you will see the tweezer length is 4mm. Crystal Technology tweezers are 6mm. This provides 50% more tweezer length, which makes the unit more functional and, therefore, more effective. Width – Tweezer thickness on traditional epilators is .8mm. The Crystal Technology tweezer width comes in at a robust 3.8mm. The wider tip makes for a better epilation experience, as a wider tweezer head is far more comfortable than the dinky little tweezers on other epilators.
