Available for immediate purchase. This is an external HDD made by Buffalo. I purchased it from Yodobashi.com in December 2025, but it was larger than I expected, and I don't think I'll have a chance to use it, so I'm putting it up for sale. I connected it to a computer only once to check its operation, but it's otherwise unused. I cannot include or send the purchase receipt because it contains personal information. Also, the product can be shipped immediately, but delivery may be delayed due to the New Year's holiday period. Thank you for your understanding. Operation confirmed. External dimensions (width x height x depth): 114 x 33 x 171mm *Body only (excluding protrusions) Thank you for looking.
