Hi disujamariya, Here I recommend seamless acrylic paper weight for your reference.
For you information, Acrylic paper weight: It is with high-transparency, and webding photos, coins, metal sheets, stamps and drawings etc. can be inserted in the middle. It is in a vacuum condition. The both side of the product is quite smooth and seamless with no chink or sharp angles. It can also be stored for a long time without changing any color, thus it’s of high value to save as a souvenir or collection.
Maybe you can access
