Seaside Summer Holiday Mini Postcards Set — 10×10 cm | Zolota Ptakha

A quiet seaside mood across four cards — a mint square with “Happy Summer” beside a palm frond and rolling waves, a diving swimmer next to “Happy holiday”, two paper sailboats around a single “Summer”, and a sunny yellow card carrying a starfish under “summer holiday”. The 10×10 cm format on 350 g/m² stock is the size of a real holiday note — easy to write, easy to send.
