Review on 🔌 USB Flash Drive Case - JBOS Storage Bag for USB Drives & Electronic Accessories - Organizer for USB Flash Drives, Thumb Drives, Jump Drives - Ultimate USB Holder & Organizer by Jenny Washington

I bought them for a conference and 3 flash drives out of 10 did not allow me to add data, constantly gave an error code that the flash drive was full of data on it weren't, the rest worked fine. I couldn't go back because there wasn't enough time before the conference to buy new ones so I basically bought ten for the price of seven and had to buy more at the local store to buy them. This is my first time buying Revain flash drives and I haven't had a problem with any of them.
