Dear PSBWB, Please confirm the specifications for the EP record frame you ordered. We have made it in a size that also fits the standard EP jacket size of 182mm x 182mm. We propose a specification that accommodates the jacket size of 170 x 170 you ordered by inserting spacers on the four sides (see photo 4). With this specification, you should be able to use it even if you change the records you display in the future. Please confirm. If you have any questions, please feel free to contact us.
