with out Perforations:

The RL3356XW does have perforations between labels. At this time we do not offer custom sizing or configurations for the inkjet roll labels so we would not be able to produce this product without perforations. If you have any other questions regarding this or any other product, please feel free to reach out to Customer Support at 888-575-2235 or by submitting a support ticket at the link below: https://www.onlinelabels.com/Support/SupportRequest.aspx

Do any of these come off of surfaces well? Preferably glass/windows?

The Weatherproof White Matte (JW) is a durable, polyester-based material so it does not rip or tear easily when removed like paper-based labels. However, the permanent adhesive may leave a residue behind.
