Undoubtedly it’s a SIM (Subscriber Identity Module) card-shaped notebook. Although it can’t help you to connect any caller, yet it can save your phone numbers just like the real SIM card.
The SIMbook notebook measures 135 x 85 x 15 mm, and looks really like a giant SIM card. Apparently it’s impossible to plug the SIM card into your cell phone, but it’s entirely suitable to your various bags. Of course, it can store many phone numbers, messages, and memos as well as the real SIM card.
SIMbook notebook is priced at $3.78 USD. If you like the unique notebook, it’s available at FindMeAGift.
