Expresii (www.expresii.com) is a new painting app featuring advanced brush and ink (watercolor) simulation for Windows. After purchase you get a PDF with a download link or you can download it directly via: http://bit.ly/1jSnKny . Currency is USD.
Warning: Expresii uses modern GPU for accelerated processing therefore it may not work correctly on older computers/drivers. Get a free key via https://gum.co/expresii_trial and make sure it works well (including saving function) on your computer before any commitment.
Note to Korean user: Gumroad only accept Credit Card owner's address in English so please do not enter your address in Korean.
建議先到這裡拿個免費 ‘試用Key’ ：https://gum.co/expresii_trial . 有了‘試用Key’ 才可有儲存的功能。把儲存功能也試好，覺得沒問題才回這裡買Full Key。
