A retro, postal-themed collection of stickers designed by ob1toy for Sanby. These "multi-stickers" can be adhered to a variety of surfaces, including fabric, leather, glass, wood, metal, even ceramics. No ironing required, though ironing can improve adhesion to fabrics. Once fully adhered (24 hours), they're even dishwasher and washing machine safe! Each sticker can be applied separately. Please visit JetPens for an English translation of instructions.
