bamboo basket
籮 centers on a container woven from bamboo: a basket used for carrying or storing items.
籮 combines 竹 (bamboo) with 羅, which likely contributes the sound and the idea of a net or mesh, suggesting a woven bamboo container.
The top 竹 is bamboo, and the bottom 羅 suggests a net or mesh. Picture a basket woven from bamboo strips, like a net made solid.
For ラ, imagine a large bamboo basket labeled with the musical note 'la': la -> ラ, and the basket is woven from bamboo.
