Djuiinostar 4In Spinning Top Base, Highly Polished By Hand, -30Cm Focal Length (Single Concave), Diameter 3.9In/10Cm, Thickness 0.55In/1.4Cm, Weight 0.54Lb

POLISHED RIM&EDGE: The rim at the dented side is highly polished to avoid any potential hurts to your beloved spinning tops; we also polished the edge to make this base look nicely on your desk. Each base is designed to be a spinning top base and highly polished by hand, so please dont simply compare its price with those roughly made lens on the market.

THICKER&HEAVIER: Unlike lens, this one is thicker and heavier. This ensures that it can provide stability (less vibration/movement/voice) for successful spins.

FOR SERIOUS PLAYERS: This base is designed for people serious on spinning tops. With the help of this base, you can get much better gaming experience. Your spinning top will freeze on the base for a while.

Diameter: 3.93±0.05inch; Thickness at edge: 0.55±0.05inch; Net Weight: about 0.54lb; Focal length: -30cm; Single Concave.
