Passive dehumidification with silica gel
Help keep the air in a closed storage box dry. Silica gel absorbs moisture while our containers hold the beads in place.
Place silica gel inside a closed space when storing filament or other moisture-sensitive items. Perforated walls and lids expose the beads to the air; a press-fit lid lets you inspect or replace them. Every white PETG container comes with indicator silica gel.

Frequently asked questions
Is silica gel included?
Yes. Every model comes with indicator silica gel, the container and its lid.
Can beads fall out?
The lattice openings are about 1.6 mm and designed for 2–5 mm beads. Check the size before refilling with other beads.
Which one fits my box?
Measure the available space: the round model is Ø50 × 30 mm; the corner models use a 50 × 50 mm base and stand 50 or 100 mm tall.
Will it dry filament that is already damp?
No. Silica gel helps control air humidity during storage. A damp spool needs to be dried before it is stored.
