I initially bought a big pack of mini dry erase markers off Amazon to replace my marker when it died. The knock-off ones stained my dry erase board and dried up so quick. And they did not fit all the way into the cap provided by ScribePad. I got tired of my marker never having ink when I went to write with it so I ordered a 3-pack of makers from ScribePad and I wish I would have just ordered additional markers from them in the first place. They don’t dry up super quick and they keep their pointed end better than the knock offs. Just skip the bulk knock off brands and buy you some more markers from ScribePad to start with!
