Rumat Studio's online store opened in October 2025, at which point a few patterns were released for sale. Now, for the first time, a small batch of physical products is available for purchase. The products are handmade in Suomussalmi using recycled materials.

Kokalmus is suitable for everyday use and withstands heavy wear. The Kokalmus bag has a zipper to keep items secure. Its strap is detachable and easily adjustable.

Kokalmus is designed to minimize cutting waste, thus reducing the loss of valuable materials.
