Boveda 1g 58% Slim Humidity Control Packs, 1,500 Count
A rectangle rather than a square, the 1 g slim pack is shaped to drop straight down a narrow pre-roll tube. It holds up to an eighth, or 3.5 g, at 58% RH — the drier of Boveda's two flower levels. Same fill throughout: food-grade salt, purified water and a thickening agent.
A Rectangle Format at 58% for Pre-Roll Tubes
Shape is the reason this SKU exists. A square 1 g pack will not lie flat in a standard pre-roll tube. It cants across the diameter and fights the cone going in. The slim runs the length of the tube instead, which is why pre-roll lines at 1,500 per case reach for it. At 58% it holds drier than the 62% version, which suits product sitting in inventory rather than shipping out.
Key Features
- Slim Rectangle Format: Runs the length of a narrow pre-roll tube instead of canting across its diameter.
- 58% Two-Way Control: Adds moisture to a tube that has dried out and pulls it back after it is opened.
- Holds Up To 3.5 g (1/8 oz): Matched to single-eighth tubes rather than full jars.
- Pure Water Vapor Only: A reverse-osmosis membrane means nothing but water crosses into your material.
- Safe in Direct Contact: Rated to rest against a pre-roll without affecting flavor or aroma.
- 1,500 Packs per Case: Packaging-line volume for continuous pre-roll fill.
- No Activation Required: Active on arrival, so there is no soaking, charging or maintenance step.
- Drier Than 62% RH: The right level when product sits in inventory rather than moving quickly.

Why Choose Slim Over Square?
A slim rectangle lies along the length of a narrow pre-roll tube. A square pack cants across the diameter and gets in the way of the cone.
Boveda 58% or 62% for Pre-Rolls?
58% suits product sitting in inventory or moving through a long supply chain. 62% keeps more moisture in for fast-moving stock.
How Much Does a 1g Slim Pack Hold?
Up to an eighth, or 3.5 g — the same capacity as the square, just in a different shape.
Is Boveda Safe Touching a Pre-Roll Directly?
Yes. The membrane releases pure water vapor only, so nothing crosses into the material it rests against.
