How do I recharge the desiccant packs?

When the indicator dot turns pink, recharge the pack in an oven or microwave following the printed instructions. Each pack can be recharged and reused for years.

Nylon (PA), TPU, PETG and PVA absorb moisture fastest. For these we recommend our aluminum foil bags, which also block UV light. PLA and ABS benefit from dry storage too.
