You may have notice recent orders of spares packaged in generic clear packaging (SKU starting with 2/3), here is why. those are internal sub spares are does not have set packaging. To account for additional labour to package specific spare at bulk or before dispatch some items have increase to cover these associated costs. As we still continue to test batch specific common failure parts such as thermistors/hotend, with all parts visually inspected before dispatch. For seal product, seals are checked before dispatch ensure parts are supplied as New Condition.
