Human Grade Downstems - Various Sizes

The Human Grade Downstem is a straightforward replacement part built to bring an older or damaged piece back to full performance. Handmade from thick borosilicate glass, it's available in every popular length from 3" up to 6" in half-inch increments, and it comes in either 10mm or 14mm joint sizes, so finding the exact fit for your piece shouldn't be a guessing game. Diffuser slits at the bottom break smoke up for a smoother, quieter pull, and the glass stays crystal clear so it looks as clean as it performs. Highlights:- Available in 3" to 6" lengths- 10mm or 14mm joint sizes- Diffuser slits for smoother, quieter hits- Ruler printed on packaging for easy measuring- Thick handmade borosilicate glass- Intended for legal use only *Per industry standard, length is measured from the bottom of the frosted joint to the tip of the downstem — not the overall end-to-end length of the piece. However, Human Grade measures the entire length of the downstem. Please subtract 1 inch from the overall stated length to get the industry standard measurement. See our Downstem Measuring Guide for details.*
