Permanent marker can often be removed from a smooth plastic surface, but the safest method depends on the plastic and its finish.Ink may sit on top of polypropylene, polyethylene, or another non-porous surface. On soft, textured, aged, painted, or transparent plastic, the ink may penetrate scratches or react with the coating.

There is no single standard volume for every plastic water bottle.A small bottle may hold 250 or 330 milliliters, while common retail bottles may contain 500, 600, 750, 1,000, or 1,500 milliliters. The correct amount is printed on the label.

Plastic can be cut with a utility knife, scoring tool, saw, rotary tool, pipe cutter, or industrial shredder. The correct method depends on the plastic type, thickness, shape, and required edge quality.
