Here we have 35.5in x 15.75in x .11in (90cm X 40cm X .3cm) large style vape mat. Please beware that these are multiple feet across in diameter!
These things are incredibly well made. The color on them is fantastic and we've had testers at corporate for months in our builders area and they hold up to some heavy duty wear and tear. If you need a mat to build on or even just a nice surface for a mouse/keyboard, these things will blow you away.
