Where can I buy moving blankets in Tainan

Trying to find moving blankets like this: https://www.amazon.com/ABN-Universal-Utility-Protection-Blankets/dp/B01MYBNJW1/ref=sr_1_16?ie=UTF8&qid=1516084888&sr=8-16&keywords=moving+blanket&refinements=p_n_shipping_option-bin%3A3242350011

I live in Tainan and have no idea where I can buy these. My Taiwanese friends act like they don’t even know what this are. I’m going to use them for sound dampening in my apartment.

I’m not sure where to buy them except online. https://www.1688.com/chanpin/-B0E1BCD2CCBA.html
I’m sure if you show them a picture of a 搬家毯子?I see them inside of elevators to protect the walls when people are moving, so they have to be here somewhere.

I would love to know this for Taipei
