Teething issue for startup
Card was left hanging in Singapore for 2 mths Before sending to US. When return, collection was via just name and no other form of order ID or Cert Number or collection notice. This kind of collection process is just so insecure.

Thank you for your honest opinion, we will improve our collection process and experience in the future. Looking forward to seeing you grade with us again.
Amazing experience
I find the concept grading is very trustworthy and can check the card for grading before sending to grading. The grader provides best service such as communication, and meeting to check the card condition. If the card is not in good condition, he will comment to avoid sending for grading.

Journey through concept grading
Started my slab grading journey through concept grading during a trade show at concept city. The grader MR. SW was very patient, kind and professional during the entire experience and gave meaningful suggestions as well as insights on if a card should get graded. Have graded a few cards during my first round of grading and most of the results are above my expectations. Looking foward to grade with concept grading again. :)
TCG PRO GRADING SERVICE!
Concept grading is very professional in what they do best. They do pregrading for TCG and they provide pre-grading service so that u can decide whether the cards are worth sending. My experience has been awesome and grader Shi Wei is very professional and friendly. They even has a website to update u on the grading process (aplus pt for me). Try it yourself and u will know.
