Boveda 1g 62% 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 62% RH, moving pure water vapor either direction as the tube drifts. Same fill as every Boveda: food-grade salt, purified water and a thickening agent. Placement is the entire point. A tube has one usable space, and it is the gap along the wall. A square pack cannot use that gap without canting across the diameter. The slim runs the length of the tube instead, sitting clear of the cone as it goes in.
A Rectangle Format Built for Pre-Roll Tubes
Shape is the entire reason this SKU exists. On a line the sequence is short: pack in first, cone in after, cap on. The pack goes down the side rather than on top, so it never fouls the seat of the cap. At 1,500 per case there is enough depth for a real production run rather than a sample. Nothing needs activating, because the packs are live on arrival. What that means in practice is that an opened case works against the room, so stage a run and reseal the rest. Replace on roughly a three-month cycle, reading the pack by feel rather than by a card. For jars and wider tubes the square version is the better fit.
Key Features
- Slim Rectangle Format: Runs the length of a narrow pre-roll tube instead of canting across its diameter.
- 62% 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.

Slim or 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.
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.
How Long Does a Slim Pack Last in a Tube?
Two to four months typically. A sealed tube that stays shut runs longer than one opened daily.
