For sale is a jumbo size metal ball winder. This model is custom made under the brand name of "Stanwood Needlecraft" and exclusively distributed on Amazon by us (Oriental Touch LLC). The quality of this machine is superior. It is heavy duty and built to last. Comparing to other models, our model has the following advantages: (1) We use special nylon material for cogwheels. They are super strong but make much less noise than the metal cogwheels. (2) Our model does not require tools to assemble. (3) Our frame is painted by electrostatic paiting so paint won't come off. (4) The edges of this machine are super smooth. It won't leave any marks on your table. We are very proud to finally offer this large model. It can handle about 10 oz of yarn, which is 2.5 times of what our smaller winder does. The winder can be clamped onto a table up to 2 1/8" thick. The picture shows how it winds an 11 oz yarn ball (Yarn ball is not included in this sale).
