ID Tags for your Circular Needles! From Nancy's Knit Knacks.
These little highly engineered plastic tags are designed to snap onto your cables and not fall off.
Each Tag has little "barbs" that keep the cable from slipping out through the slot when they are installed on your needle. Yet, give them a gentle tug and they are easily removed. They will not fall off accidentally, either. They simply work great.
ID Tags are extruded from a special plastic and the needle sizes are then "etched" into the yellow surface. The black numbers will never wear off.
ID Tags are put up in sets of 29 tags. Each set has multiple ID Tags for each needle size. The more popular needle sizes within each set have 3 or 4 tags each.
