Will cleaning improve my grade?+

Cleaning can improve a card's presentation by removing fingerprints, oils and surface grime, which may help your card look its best on grading day. The final grade is decided by the grading company, so we can't guarantee a grade increase.

Do you guarantee grading improvements?+

No. We never guarantee grade increases, scratch removal, or value increases. We focus on what we can control: careful, professional cleaning that helps your cards look their best. Results vary depending on card condition.

How long does cleaning take?+

Most orders are returned within 5–10 working days from arrival. Larger or bulk orders may take longer; we'll always confirm timing when we quote.

What cards do you accept?+

Pokémon, Yu-Gi-Oh! and Sports Cards (football, basketball, baseball and more). If you have something unusual, just ask; we're happy to take a look.

How should I package my cards?+

Each card in a penny sleeve and toploader (or semi-rigid), then in a sealed plastic bag, then in a padded mailer or small box. For higher-value cards, use a tracked & signed-for service and ask us first for guidance.

What if my card is worth over £1,000?+

Get in touch before shipping. We'll talk through extra precautions, suitable insurance, and a recommended courier so your card is fully protected door-to-door.

Do you offer bulk discounts?+

Yes. Submit the contact form with order type set to Bulk Order, include photos and quantities, and we'll put together a custom quote within 24 hours.

Who pays shipping?+

Customers pay shipping to MJs and pay return shipping. Orders valued above £100 qualify for free return shipping. Cards valued above £1,000 should be discussed before shipment.
