This is a TOM-type Nashville-style bridge removed from an Epiphone Casino. It will be shipped in a GOTOH box. Regarding dimensions, I believe they are almost the same as GOTOH's "GE103B-T," so please refer to its dimensional drawing. Due to the nature of the product, some modification or adjustment to your guitar may be necessary. Returns and refunds due to the buyer's circumstances after shipping (e.g., not reading the description carefully, no longer needed) are not possible. Thank you for your understanding.
