NICESHNicesh Plastic Cutting Board Set - Thin, 11.8" x 7.8", set of 4

Are these flexible

for camping purposes ... how much does just one of them weigh? thx

The description says the boards are .87 (or 3/4"), but you answered users asking the thickness as being .125 (or 1/8") inches so which is it?

are these dishwasher safe?
