C-Line Binding Bars Only, 40-Sheet Capacity, Black

I actually got these to use with plastic mesh for aquarium dividers. They worked perfectly for my 10 gallon and 20 gallon long. I had to make a couple of cuts to shorten them and they cut up the middle with scissors and snapped off perfectly to size. Turns out these can be a nice versatile product. My 5 year old will be using them in the future and I now have my 10 betta fish nicely divided among a 10 and two 20 gallon tanks. So worth the price and Much cheaper than actual tank dividers. Add a few bent large paper clips that mimic the clip holders on the expensive dividers and these hold as tight as store bought.
