UPGRADED: We especially designed and used a new nice packaging, ensures nothing broke during transportation than others. We also upgraded the needles, made them not sharp anymore, you won't get hurt when you install them!GOOD QUALITY: The handle is made of aluminum and the surface is polished. The ergonomic shape design makes it comfortable to hold. The needle is made of high-quality stainless steel, rust-proof, anti-corrosive, durable and safe to use.WHAT'S IN THE PACK: One pack includes 1 handle and 10 needles, the handle includes 8 slots to arrange, totally 10 needles (2 for spare use)HOW TO INSTALL: 1. Put the handle upside down on the table. 2. Insert the needles vertically into the slots. 3. When you first insert the needles, you will find there's styrofoam in the slot, the purpose for it is to fix the needles in the slot, prevent the needles fall off, so you have to puncture the foam with certain force.
