The SEIRIN D-Type is a tube-free needle designed for ear, hand, and scalp points where guide tubes get in the way. At 15mm, it's purpose-built for shallow insertion using one-hand techniques. The lightweight color-coded plastic handle keeps the needle from tipping after placement, and the SEIRIN tip polish delivers the same smooth insertion the brand is known for.
