【Interior Encyclopedia】 This is a CD-ROM I purchased 5-6 years ago to obtain an interior coordinator certification. I ended up not taking the exam, and this product has been sitting at home after being opened and used once. The CD-ROM contains data for 1,594 flashcards, which can be printed and used as ring cards. (※ You will need to print them yourself) ・You can view the "flashcards" one page at a time on devices that support PDF files, such as smartphones, tablets, e-readers, and computers. ・If your device supports multitasking, you can also view the cards while listening to the MP3 audio explanations. I highly recommend this for those aiming to obtain an interior coordinator certification. Please refrain from purchasing if you are concerned, as this is a used item. There are signs of opening on the packaging.
