{"type":"firestarter.listing","listing":{"id":"lst_TEtjtrJ2","product_name":"Humidipak Bulk Packs","category":"D'Addario","description":"The D'Addario Humidipak is the only maintenance free, two-way humidity control system for guitar.  It automatically maintains the optimal 45-50% relative humidity level within your instrument case, eliminating the guesswork and potential mess related to refilling a humidifier.  Unlike refillable humidifiers, the Humidipak system provides true “two-way” purified humidity control by adding and removing moisture on demand.  No more manual adjustments based on seasonal changes, geographic locations, temperature, or other factors.  Humidipaks last between 2 and 6 months and should always be kept in a sealed environment like a hard-shell case.  Once the Humidipaks become firm, discard and replace.","images":["https://cdn.shopify.com/s/files/1/0669/6042/5025/files/da_PW-HPRP-24_main_transparent_web.png?v=1773014146","https://cdn.shopify.com/s/files/1/0669/6042/5025/files/da_PW-HPRP-12_main_transparent_web_a1169326-8e29-4783-85bf-b04592c98cd3.png?v=1773014146","https://cdn.shopify.com/s/files/1/0669/6042/5025/files/da_humidipak_EnhancedImage1_transparent_web_138f89e6-6958-44e5-88fd-13b990a872ae.png?v=1773014147","https://cdn.shopify.com/s/files/1/0669/6042/5025/files/da_humidipak_EnhancedImage2_transparent_web_cb511f99-ae4e-451f-95ba-10346217aa07.png?v=1773014147","https://cdn.shopify.com/s/files/1/0669/6042/5025/files/da_humidipak_EnhancedImage3_transparent_web_2dce9334-05be-48cb-bcee-2ef5e4ada0e9.png?v=1773014148","https://cdn.shopify.com/s/files/1/0669/6042/5025/files/da_humidipak_EnhancedImage4_transparent_web_d6675e4b-879b-40be-b266-71b6ff26d1ef.png?v=1773014148"],"price":64.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:55:57.980Z"},"share_url":"https://firestarter.network/l/lst_TEtjtrJ2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
