This is a shredder made by IRIS OHYAMA. A4 size compatible. CD 5-split compatible. Operation has been confirmed. The paper shredder works without any problems, but I have not confirmed the CD shredding function as I have never shredded a CD. The switch button is a little stiff, and there is a feeling of use, so please purchase if you understand that this is a used item. I will disinfect and clean it before handing it over. - Brand: IRIS OHYAMA
