Exhibition Amper had its world premiere - this 4-SIM-card-holder was introduced for the first time here by the OREO Praha company and was invented by a Czech person. Why was it a SIM card holder that was introduced? There are several reasons and many of us experienced at least some of them. Some managed to lose their SIM card, some broke it in their pocket, or it was damaged due to static electricity. Our SIM-card-holder is here to prevent your SIM cards from being lost or broken and keeps them all together in one place in your wallet.
