Non-UMEMARO 3D Work/LINE Stamps

Under his non-erotic persona of Oresamax Yojinbo, UMEMARO has developed a consistent side-project focusing on LINE stamps, having produced 20 sets to date.

Background
LINE is a Japanese instant messenger application available on both mobile and desktop devices, supporting most major mobile and desktop operating systems (including iOS, Android, Windows, and macOS), originally developed internally by NHN Japan during the 2011 Tōhoku earthquake for communication, as Internet-based communication was the only method available in the immediate aftermath of the earthquake. The application has since become massively popular in Japan, and is measured as Japan's largest social network as of 2013. The application has over 700 million users worldwide, and is available in 40 languages.

One of LINE's biggest features, and the cornerstone of its success, is the wide variety of stickers produced for the application that can be sent to friends as emoji-style reaction images. From Wikipedia:

"Line features a Sticker Shop where users are able to purchase virtual stickers depicting original and well-known characters. The stickers are used during chat sessions between users and act as large sized emoji. Users can purchase stickers as gifts, with many stickers available as free downloads, depending on country availability. Purchased stickers are attached to an account and can be used on other platforms. New sticker sets are released weekly. Line's message stickers feature original characters as well as a number of popular manga, anime and gaming characters, movie tie-ins, and characters from Disney properties such as Pixar. Some sticker sets, such as those that celebrate special events like the 2012 Summer Olympics, are released for only a limited time. Default stickers were designed by South Korean artist, Kang Byung-Mok, also known as illustrator Mogi.

There are over 1 billion stickers sent by worldwide users on a daily basis."

Releases
Oresamax posted his first collection of LINE stamps, focused on a 3D rabbit, on March 28, 2015. He introduced the popular Frog character in April 2015, releasing eleven installments of that series as of 2019, though he has sporadically interspersed sets based on hamsters, rabbits, and cats between the Frog series releases. Production of LINE stamp collections tends to occur in the immediate aftermath of an UMEMARO 3D release, often as a cool-down from the stressful production cycle for those releases. Sets are priced at $0.99 USD for non-animated sets, and $1.99 USD for animated sets.

Rabbit Plush
Rabbit Plush is Oresamax's first collection of LINE stamps, released on March 28, 2015.
