Ninja Glass

Ninja Glass is our house label for fast-turning head-shop essentials—clean designs, everyday pricing, and retail-ready packaging that makes the counter hum. The current lineup keeps choices simple and profitable: 40 mm 4-part grinders (1.5″) in durable aluminum or eye-catching rainbow zinc alloy—including windowed and skull-accented styles—and a pocket-friendly 650 mAh 510 battery kit with an LED display that shows voltage and battery level. Assorted colorways look great under LEDs, while standard features (kief catcher, smooth threads, and charger included on the battery kit) give staff quick talking points that convert browsers fast. Order with confidence through SPS Wholesale’s wholesale-only program—$100 minimum and fast California fulfillment—and refresh your head-shop supplies with reliable, margin-friendly retail smoke gear shoppers will actually use.
