Frequently Asked Questions
Yes, always. Every product we sell is sealed and sourced authentically. We're collectors ourselves — we'd never sell anything we wouldn't buy.
Most orders are dispatched same day or next business day. Delivery typically takes 2-5 business days depending on your location.
Once your order ships you'll receive a tracking number via email. Use that to follow your parcel every step of the way.
We don't accept returns on sealed products unless the issue is on our end — wrong item sent, damaged in transit, that sort of thing. Because we deal in sealed collectibles, we can't accept returns on opened or handled product. This protects every customer from receiving tampered goods.
