First of all, let me apologise for the terrible quality of photos. I had limited space to work in when I did this project and only a phone camera, so the lighting isn’t great and the resolution is rather low. Hopefully everything is clear!
Twinsaver (and maybe other brands I don’t know about) sells these really nice tube shaped tissue boxes. They’re narrow and compact, made of thick durable cardboard, and have a nice plastic ring at the top so you never accidentally rip the box when you try to open it. But they’re also pretty expensive and only hold 80 tissues per box, so we get through them really quickly.
