Ordering is simple: add boxes, tap My Order (bottom right) to send it, and you receive payment instructions. You never pay on this site. Bulk orders: ask about volume pricing.
How ordering works
- Add boxes to your order (minimum one box per product).
- Tap the My Order button (bottom right), check your boxes, then tap Continue.
- Enter your shipping details and tap Send My Order. You get an order number right away.
- You receive payment instructions for your exact total.
- Before shipping, MMK sends you pre-shipment photos and your order number to confirm.
- Texas orders ship within 48 hours by UPS. China orders ship the next day and arrive in 5-8 business days. No weekend shipping: weekend orders ship Monday/Tuesday.
How to pay
Option 1: Crypto (no fee). Send USDC (stablecoin) or BTC directly to the wallet address you receive with your payment instructions.
Option 2: PayPal, credit card or Alibaba (+6% fee). A 6% transaction fee is added for these payment methods.
New to crypto? It takes about 2 minutes:

- Tap Send, paste the wallet address from your payment instructions, and send the exact amount.
- Put your order number in the note if the app allows it.
