I found a Thai-rated stamp in the offline market. I have never played stamp collecting before. What about this rating company?

Yuan Tai's score is very good. Their home is the rating agency that I have been most assured of playing stamps in recent years. Their family is the earliest stamp rating in China, and their qualifications and professionalism are also the top level in the industry. The rating of rare philatelic products is also the highest in the industry, and people in the industry are well-known. Moreover, this packaging shell is also very reliable, which is a national patent design, protecting stamps from moisture and ultraviolet rays, and can well protect the appearance of tickets!
