High-quality cork granules; 0.5mm – 1mm in size. The safest eco-friendly way to make wafters and pop up’s, without using inorganic material such as silicone powder or generic pop-up mixes. This product is safe for fish and wildlife. For use in hook baits only. May be added to any base mix, especially the pre-prepared dedicated ‘JB’ Hookbait mixes. Use appx. 5-7% by weight to make wafters and appx. 10-15% for pop up’s. Depending on the density of the base mix, some variation in the amount used will be required. Ensure that all hookbaits made with cork granules are rolled carefully and air dried naturally for 12 -18 hrs.
