First time trying to send cards for grading and decided to give it a try with conceptgrading. Went down for pre grade before sending my card for actual grading with PSA. Recently received good news via email notification on the Site that it was a Gem-mint 10 for the card I've sent. Kudos to Pregrade from them and their services. Will for sure send cards for grading thru them again!!!😁
Concept Grading’s boss Shi Wei is a nice and friendly guy that helps with pre-grading. Very patient and knowledgeable for pre grading or TCG related enquiries in general. Highly recommend to look for them for pre-grading.
Constantly updated and hassle free,highly recommended.
My 1st PSA submission was with Concept grading on October 2022 and the return was amazing! Gotten myself a sequential eeveelution vmax alt art. Concept grading staff was helpful and professional with the pre-grading. All my cards are handled with care. Submitted my 6th batch of PSA submission to them 2 weeks back!
Great service. Even provide free pregrading service and very knowledgeable.
Hassle free to send the cards for grading. Pre checks are also done to confirm if we want to proceed. Excellent
Very pleasant grading services, Was new to Card grading, but the grader was very experienced and clear throughout the whole process. He won’t try to sugar coat your card condition just to get you to grade. The whole process is very transparent also, the whole process can be tracked on their website, such as the flight delivery to PSA facility and back. Very happy to have received back all my slabs in PSA 10 Slabs! Very satisfied that I already have sent more cards to grading already through conceptgrading
Ask for Shiwei, knows his stuff, great service
Friendly, reliable, and always going the extra mile! Real professional service, will pre grade to check your cards and tell you roughly what the result might be to see if its worth to be graded! Educates us on the process, always there to answer any questions I have even on whatsapp! Really thankful for the existence of ConceptGrading!
Went down personally to concept city and was very glad to have met KS, who unreservedly provided a greenhorn like me with much learnings on card protection, card grading requirement and card appreciation. The experience was great and would definitely return for more advice and card grading!👍
First time buying pokemon cards from live stream, I was surprised that the card that I wanted was gotten within the box that I bought, I am so grateful and appreciate the free gift that was given & would buy again and I wan to say thank you to cancan for the opening too
first time trying to grade my cards, experience at concept city was great. pre-grader was helpful in helping in advising what’s worth grading based of your preference for grading.
