Key features

• ★NO WORRY: We provide free replacement if base broken within 3 months.
• ★LONGER SPIN TIME: hard and smooth surface extends spin times greatly; concave surface keeps your spinning top stay on the base.
• ★EASY TO USE: double concave with ideal -30cm focal lengths, suitable for most spinning tops and gyroscopes; 10cm diameter is big enough for easy spins. After practicing you can easily prolong the average spinning time on this base.
• ★CORRECT MATERIAL: made by polished K9 optical glass which is hard, smooth and heavy; edge and rim is covered with silicone which can help to keep the base in place for long spins and preventing your beloved tops from scratching in the meanwhile. At the beginning of one spin the top will oscillate on a certain orbit, our product can reduces this energy lost to a minimum.
• ★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. It helps the top get into a stable and quiet state more quickly: your spinning top will be "frozen" on the base for a while. More fun! If your goal is 3 minutes, this base is not for you; if is 5+ or 8+ or even 10+ minutes (in this case spinning top and skill matter too), you can have a try.
