RAINBOW THREAD COG DUAL ARM 21G/110/420

Dual Arm is the descriptor that separates this Rainbow Thread listing from the single-arm cogs, and the full specification reads 21G/110/420. The 21G gauge falls between the heavier 18G and 19G entries in the family and the noticeably finer options further down the range.

One quirk worth knowing if you browse rather than search: it is filed in our Needles category rather than under the brand. Clinics restocking sharps and threads in the same session will therefore find it beside items such as the Mesbio Magic Needle for U225 Mesogun 32G/8mm, which sits at the opposite extreme of the gauge scale.

Supplied sealed, priced for trade, and despatched worldwide to qualified practitioners. Consolidating threads and needles into a single order keeps freight sensible on international consignments, and clinic accounts can add other lines to the same shipment.
