WARM TIPS REMOVE TIPS:For preventing the gel sticking to the brush or other poly nail gel tools, you can dip the brush in slip solution or 70 isopropyl alcohol, so the poly nail gel can be picked and formed on dual forms smoothly. LONG-LASTING EFFECT TIPS:Modelones poly nail gel nails will last up to about one month or longer with proper nail prep (filing, buffering, and cleaning ).

What's more, you can refill your nails about every two weeks when the new cuticle area grows.
