The company's Modern Family collection has been created in partnership with Croatian designer Jagoda Jurisic, whose felt flags are handmade in her Berry Bright Factory in Zagreb.
The range features five different bunting designs, each attached to one of Plumen's Drop Cap pendants and energy-efficient bulbs. Both the Baby Plumen and Plumen 002 LED are compatible with the design.
Colour combinations include rainbow brights, pastels, monochrome with a single pop of colour, and animal print. The flags are set along the lamp's cable, which can be twisted into various configurations.
One design, titled Colour Me Happy, is intended to be educational, with flags in secondary colours arranged between the primary colours that create them.
"When we started to see the Berry Bright Factory bunting cables surface on Instagram, huge smiles opened up across our faces," said Plumen founder Nicolas Roope, who launched the company's first bulb in 2010.
Since then the company has steadily expanded its lighting range, releasing a hat brim-shaped shade in 2015 that could be slotted onto Plumen pendants.
"These colourful, handmade designs would lift the spirits in any space and fill it with happiness so we decided to offer them on our webstore to help spread a little joy," he added.
Several companies launched furniture and toys for children at this year's Milan design week.
"It is a huge market with very high potential, and many offers in terms of furnishings and toys," Kartell president and CEO Claudio Luti told Dezeen.
Other brands that have designed kid-friendly products include Italian brand Magis, which worked with Big-Game to release a chair that could be adjusted as children grow, and Gebrüder Thonet Vienna, which created a bent-wood version of a rocking horse.
