FAQ

  • At Roll Block, we specialize in curating always-in-season products and exclusive drops. Some of the items featured in our customer review photos—such as our previous summer-exclusive gear—were part of a limited-edition run sold out last summer. Because we rotate our catalog to bring you the freshest, highest-utility gadgets on the market, once a seasonal item sells out completely, it is removed from our active storefront to make room for our newest drops. We love showcasing our community's real photos, but please note that our inventory moves fast off the block!

  • Yes. This item is a Roll Block™ Authentic Edition product. Every unit is sourced, inspected, and verified directly by our team to guarantee it meets our standards for performance and design before it ever reaches your doorstep.

  • This water gun is electric-powered and requires 4 AA batteries (not included) for motorized rapid-fire action.

  • All have an effective range of up to 10 meters (~33 feet). The motorized pump ensures that your stream stays steady, tight, and highly accurate across the yard, beach, or pool without dropping off mid-flight.

  • We build our gear for real-world action. The structural shell uses premium-grade, Impact-Resistant ABS plastic. It is specifically engineered to endure the regular drops, bumps, and fast-paced movement of outdoor summer play.

  • To cut down on waste and offer the best possible value, we utilize a Streamlined Protective Shipping Protocol. Your order ships securely padded in dense, eco-friendly protective wraps rather than a generic, bulky retail box. This keeps shipping fast, secure, and damage-free.
