For diving: Diver's knife (TUSA), magnetic underwater notebook, and weight belt. Used over 10 years ago and stored at home. The knife has rust on the blade. The underwater notebook has traces of past records on the back and marks where names were erased. The magnetic part cannot be written on, probably because the pencil has deteriorated. It could be written on with other pens, so only the pen needs to be replaced, but it will be delivered as is. The belt looks to be in good condition with no noticeable damage, but it has been used many times. All items were used many years ago and stored in a closet for a long time. I think they can still be used, but they are used items from many years ago, so please understand and accept this! ◎Instant purchase is welcome! ◎Shipped via Mercari delivery. ◎If you wish to purchase multiple items, please comment and I will discount the shipping fee as much as possible if they can be shipped together. ◎Please note that the packaging will be done by an amateur using recycled materials.
