"I love saunas so much, I want to wear them all the time." This pop and slightly retro neon sign-style sticker ignites the hearts of sauna lovers. The words "SAUNA," "銭湯 (sentō - public bath)," and "37 (sauna)" glow in the dark. And adorable rubber ducks and characters happily sweating. The exhilaration after a sauna and the excitement of a night out are condensed into this single sticker. The biggest point is that the shape itself is a "sauna hat." Just by sandwiching it in a clear case, your smartphone instantly transforms into "sauna spec." [Recommended Points] • Design: Color scheme inspired by retro neon tubes. In addition to the words "SAUNA" and "銭湯," the sacred number for sauna lovers, "37," is also firmly engraved. • Size: An exquisite size of approximately 5.5cm x 5.5cm. It fits perfectly on the back of general smartphones such as iPhone and Android. • Durability: Waterproof, so you can safely stick it on items that are easily exposed to water.
