This is a Letter writing set "Cow and red flower" by Tegamiya (matsumi yoshimura), who designs stationery in Japan.
The gentle-looking cows and flowers are a heartwarming letter set.
Tegamiya is the artist who inspired me to start my own store, and I started this store because I wanted to sell her products.
