The first line of Guillow's balsa non-flying shelf model kits consisted of twelve different World War I biplane fighters with six-inch wingspans that retailed for 10-cents each.

Each kit contained a 3-view plan, balsa wood cement, two bottles of colored aircraft dope, a strip of bamboo for wing and landing gear struts – this was considered relatively good value for such toys at that time.

After the war, to meet changing customer tastes, it shifted its emphasis from stick & tissue kits to concentrate on the mass production of inexpensive hand-launched gliders and rubber band-powered toy planes that were sold at a variety of retail outlets.

[6] In 1953, the company introduced a line of mass produced, simple, inexpensive balsa gliders, packaged by high speed machinery.

Tiger specialized in "promotional flying toys imprinted with company names and graphics" and Comet was a "direct competitor in balsa kits and gliders".

[8] In recent years, the company has converted to laser cutting of balsa parts, resulting in increased accuracy, making assembly easier.
