This tape is truly amazing. It is VERY sticky, and sticks practically anything. After purchasing it I discovered that a local prototype department uses it constantly. I really only bought it to stick handmade boxes. I can truthfully say that it will firmly stick even the thickest card. It will also firmly and securely stick 'smooth' surfaces; i.e acrylics. Don't ever be enticed by cheaper products. Go for this Double-sided High Performance Clear Tape every time. I find that the 25 mm. is easier to handle than the narrower width. Remember - it is VERY sticky. I find that it is easier to handle if I cut it into shorter strips if I'm intending to stick a long length.
