Alternative to JetPens in Canada

Hi,

I'm looking to buy reffils for the tombow mono stick eraser. I've searched far and wide across the internet to find some that are sold in Canada but to no avail. I usually use Jetpens, but the prices in USD to CAD + shipping is just absurd in the current situation. I've looked at a lot of websites from recommended here, but I couldn't find this specific refill.

This is my favorite eraser and I just want to have more refill that are sold in Canada. Can you guys help me find this item?
