Water Quality is Key

Avoid tap water and mineral water—stick to filtered or distilled water. Tap water’s inconsistent mineral content can cause pellets to swell unevenly or deform, even with premium-grade gels.

Hydration Process

Size Check
After 90 minutes, measure pellet diameter. Ideal size for most blasters: 7.3mm. Drain immediately once they hit this mark to prevent over-expansion.

Container Matters
Use a wide bucket or bowl (the bigger, the better) and fill it with 3-4 times more water than pellets.

Timing & Agitation
Stir by hand every 15 minutes. Full hydration takes 2-3 hours. Pro tip: Room-temperature water speeds up the process.

💳Transaction and Payment Protection

Have you ever encountered these situations?

The internet is flooded with "ghost stores" that take your money but never ship your order or even fabricate tracking information. What’s even more frustrating is that when your package is unfortunately held by customs, these dishonest sellers use "handling customs issues" as an excuse to repeatedly demand complicated documentation from you, all while delaying and refusing to issue a refund—leaving you with neither your money nor the product.

We fully understand your concerns, which is why we’ve built a robust protection system that goes far beyond empty promises.

In addition to our unwavering commitment to integrity, we’ve integrated globally leading payment platforms that strongly protect consumers: Stripe and PayPal. This means that no matter which payment method you choose, every transaction is ironclad guaranteed.
