Aerlit Shuttles are engineered for optimum thread control. The shuttles are made of a special plastic which makes for a tighter bobbin fit.
Each shutle is 3" (7.5cm) long including hook x 0.75"(2cm) wide. They are available in a wide range of colours and include a spare bobbin with each shuttle.
A card of 5 spare bobbins is also available. To see the full range please click the link(s) below.
