Needles with a regular hole have a big disadvantage: putting the thread through the hole is a work which has to be done very precise and that can take a long time. These special needles solve this problem. When you hold the thread above the needle en you slowly take it down, then the thread gets in the hole by itself. U receive 12 needles in three different sizes: 4,2cm, 3,8cm and 3,6cm.
