    Optech sic pearls

    Posted by michael polsky on May 24th 2023

    Another smashing hit by the D-Nail master artisans. These pearls have brought new life to my device. The way the vibrate and spin is remarkable. Perfect vibration these are fast. I use to use two rubies and with this only 1 you need in your dish, which is what I use with it. Two spins up the vapor to hard and wastes some. One is perfect in clean dish. They are super easy to clean. I just out them in 99 iso to soak and after use and each time its like new. I was very pleased with the less expensive white ceramic pearls, but these are something else. They produce excellent vapor and taste is clean. Personally i cannot tell a flavor difference between any type of clean pearl. Its all performance and maintenance for me. These are the finest performing pearls I have ever tried. Maybe D-Nail will send me a 5mm Diamondium and ill compare and see if there is a flavor difference. You dont need many of these. As ling as you dont lose it, it should last as long as any pearl could be asked to last. I will not be going back to rubies.
