Didn't know there was a difference
.......it's one for 1st April.....
sheet styrene available in 7, 4, 3.5, 2.5 and 2mm scales. Good job I've been using 3.5mm scale styrene sheet for my HO modelling
.
Obviously the sheet store is designed fit in with their modular system and they clearly hadn't thought about A3 styrene sheets. Knocking out one of the rear side pockets would have solved the issue. Also looks the same with the shallow tool tray in the top of tool tidy - two instead of three trays would have been better.
