These are wiring devices, conduits, etc. for practice for the electrician's license exam. I purchased these for practice when taking the Class 1 Electrician's License exam, but I am selling them because I no longer need them. (Some items remaining from practice for the Class 2 Electrician's License exam are also included) All the items in the second and subsequent photos will be packed into the box in the first photo (cardboard box size 100) and shipped. I have not checked the details, so please consider purchasing based on the quantity shown in the photos. These items have been used for practice, so please understand that there are not enough of them to cover all the published problems. (Please use them only as a supplement) Also, some used items purchased from other sites are mixed in, so please do not perform actual construction. Shipping Method: - Shipping cost borne by the seller - Rakuraku Mercari Delivery (Nekopos: anonymous delivery) - Days to ship (4-7 days) - Basically, I will ship on weekends and holidays
