This is a 50wt thread mix with three neutral threads and an Aurifil Thread box that holds 12 50wt threads. The three threads included are 2024 (White), 2310 (Light Beige) and 2600 (Dove Grey). These are my three go to threads that I sew with all the time and are perfect neutrals for piecing and quilting. The three threads with the thread holder are great value and a must have addition to your sewing room!!!
