Don't just take my word for it!



Matt is the consummate professional, he has cleaned, pressed and submitted more than 250 books for me. He has gotten outstanding results with raw books as well as more bumps than I can count on previously graded books. In my opinion, you could not hope to find a better professional to handle your cleaning/pressing needs!



Matt is a pro. Not only is he top-shelf when it comes to pressing but you won’t find a better person to deal with. He is way above Jedi level when it comes to his talents



I have nothing but praise for Excelsiorcomix - always a wonderful job - his magic got werewolf by night 32 to 8.5



If I did not press comics, Excelsiorcomix would be who I would choose to work on my valuable books! I’ have seen his work and it is exceptional



Matt was very patient with an overseas customer who was a comic submission rookie. I sent a wide range of comic types (from 1971 Gold Key / Dell ... to 1990s 'Now' comics ... to recent Marvel) and Matt did an excellent job on them all. I am very happy with the whole process and the results, got some great grades. Highly recommended.



excellent communication always very helpful highly recommended



Matt is the BEST. He cares about the books he handles just as much, if not more, than his customers themselves do. That sort of passion, combined with years of knowledge and expertise, sets him above the rest. If you have high dollar books that need extra TLC, this is where they should be going.



extremely nice guy has a lot of knowledge about comics, great prices just dropped off 30 books yesterday
