This is a single-flower vase from MIKIMOTO. It has a separate design with upper and lower parts, so you can use it as a single-flower vase or as a regular vase. It's also easier to clean than a regular single-flower vase. You can also change the shape to suit the flowers. I have disposed of the box, so only the item itself will be sent. It will be packed with air cushion, etc., and a box that fits the size will be reused, and shipped anonymously via Mercari. The ruler is not included in the product. Please take a look at the images and purchase after you are satisfied. I am currently organizing my collection and have various items for sale. Thank you very much. Thank you for looking.
