Grove needles are bamboo knitting needles reimagined. The raw bamboo is treated with LYKKE's proprietary process, which enriches the bamboo to strengthen and smooth it and adds a touch of green that evokes the feeling of bamboo just cut from a grove. This is accentuated with tasteful green caps with laser-engraved needle sizes.
