Do not buy this. Waste of time. The size is not accurate. I ordered 20x20 and it didn’t even measure 19.5. And I didn’t even receive the full order. It’s supposed to be a four pack. Only received 2 per pack (4 total). I ordered 2 four packs (8 total). I have reached out to order support and no response.  Returning ASAP. It’s also over priced and not worth it if you only receive 2 in the pack.
