A skull and teddy bear oil burner pipe is a type of glass pipe used for smoking concentrates, such as oils or wax. These pipes are typically small and designed to be portable. Here's a brief description of each:

1. Skull Oil Burner Pipe:

   • This pipe is made of glass and often shaped like a skull.
   • It has a hollow body with a hole on the top (skullcap) for loading concentrates.
   • The user heats the bottom of the pipe with a flame (typically a torch) to vaporize the concentrate.
   • The vapor is inhaled through a small hole on the side or back of the skull.
   • These pipes often have artistic and decorative designs, including colorful details.

2. Teddy Bear Oil Burner Pipe:

   • Similar to the skull pipe, this pipe is made of glass and shaped like a teddy bear.
   • It has a hollow body with a hole on the back or top for loading concentrates.
   • Users heat the bottom of the pipe to vaporize the concentrate.
   • The vapor is inhaled through a small hole typically located on the back or side of the bear.
   • Teddy bear oil burner pipes also often come in various colors and designs.

Both types of pipes are designed for smoking concentrates and are heated to create vapor for inhalation. However, they have unique shapes and designs to suit individual preferences and aesthetics. Please note that the use of these pipes may be subject to legal restrictions in some areas, and it's essential to use them responsibly and in compliance with local laws.
