A tip gives one end of a hand-rolled paper structure and helps keep its opening in shape. It also provides a place to hold the finished roll. Tips sold with rolling papers are convenient because both items come in one pack, but the number of each can vary by product.

No. Paper tips and glass tips are different materials. Paper tips are generally intended for one use, while some glass tips are designed to be removed, cleaned, and reused. A tip’s material also does not automatically tell you how much it filters, so check the product description rather than treating every tip as a filtration device.

Start with the length and width of paper you prefer. King papers provide a longer format, King Slim papers pair that length with a narrower width, and 1 1/4 papers are shorter. Exact dimensions vary between products, so check the measurements on the pack if you need a particular fit.
