This item was purchased in China and has been stored for a long time. I bought it because I thought it would be satisfying just to have and look at, rather than for practical use. However, as I'm entering the decluttering phase of my life, I'm offering it for sale in the hope that someone else will purchase it. Unlike other sellers, there is no writing on the box, so I don't know much about the ink itself. Please be aware of this. Box Size: Turtle: 9.8 cm x 7 cm x 2.5 cm Cicada: 9.4 cm x 5.5 cm x 2 cm
