Dear customers worldwide, First of all, I would like to tell you this. Worldwide shipping from Tokyo is back to reasonable prices!! Due to the COVID-19 and Ukraine crisis, shipping fees from Tokyo to overseas have been rising, but things have returned to normal since October 2023. I have adjusted the shipping fee, so please check it if you would like. For example, the shipping fee for small items under 100g, which used to be $25, is now less than $10. I felt relieved. Because the shipping fee was more expensive than the work itself. Now, my works could fly more freely. Best regard niji minato >>>>>>>>>>>>>>>>>>>>>>>> This is an acrylic octagonal prism using dichroic film & prism film. When it is exposed to straight light such as sunlight, it will be split cleanly. https://www.instagram.com/p/B5fCSynD0e1/ https://www.instagram.com/p/CWHu0p0Dg1u/ If you want to enjoy at night, I recommend an LED flashlight with a spot beam function.
