- Silicone - can be soft and pliable or fairly firm depending on the type of silicone used. Some toys feature two types of silicone to replicate a "realistic" feel, and are known as 'dual density' toys. Silicone can be slightly cold at room temperature but can be warmed up by putting the toy under your arm or by running warm water over it. Though smooth, silicone should be well lubricated as it has some drag to it. There are exceptions, but generally use water based lubricants with silicone toys--silicone lubricants can degrade the silicone in the toy unless the manufacturer recommends otherwise. Silicone is also notorious for collecting lint, so it's advised to keep your toys in a box or plastic bag.
- Stainless steel and aluminum. Metals can be cold at room temperature. Metal toys can be quickly warmed by running the toy under warm water, or even intentionally heated or chilled in the freezer. Stainless is heavier than aluminum and the weight is part of its appeal. The surface is extremely smooth, and is compatible with all lubricants.
- Glass - Glass toys are made from borosilicate glass, popularly known by the trade name Pyrex. It is shatter resistant, and you'll find that these toys are not fragile and are very safe for insertion. Like metal they can be cold at room temperature, but can be warmed under warm water. You should avoid extreme changes in temperature to avoid breakage. Like metal, glass is also very smooth, fairly weighty and is compatible with all types of lubricants.
- Hard Plastic. Often toys are made from ABS plastic. Some hard plastic can be porous, and if so, it may not be sterilized or shared unless you cover it with a condom. Hard plastic is lightweight, smooth, and doesn't tend to be cold at room temperature. Hard plastic can be used with all types of lubricants.
