Bryspun's plastic knitting needles are beloved by knitters for their ergonomic design. The flexible material can offer relief from hand pain, while the matte off-white colour does not glare under bright light. The specialized needle tip is narrow to allow complex stitchwork like Estonian lace, but isn't sharp - so it won't hurt your fingers if you 'push' your tip as you form your stitches.
Plastic needles are somewhere between metal and wood in terms of grip - they are good for looser knitters who want more control and for working with slippery yarns like silk, mohair, bamboo and linen.
