The design is awful - try opening the top with sweaty hand (those of us doing physical labor) WILL NOT BUY THEM AGAIN - WILL SEARCH FOR A NEW VENDOR FOR SUPPLIES
I used to buy a lot of markers and highlighters at Staples. Now I only try them occasionally ever since they started stocking mostly the Staples brand. They are not as good. The tips don’t last as long and the ink doesn’t last as long as the name brands I have bought there in the past.
