We use TPE (or 10X) in a number of our products as it is an ultra-tough, super stretchy and durable material... The only drawback? Due to the unique chemical properties of the material, it can react and melt if stored touching non TPE plastics.
Where possible, store your TPE lure in the original packaging. This is the safest option.
TPE can also react if stored directly in certain tackle boxes or containers, so keep an eye on your stored product for a reaction within 24 hours.
REMEMBER: You can store TPE products together, but they must be kept separate from other Non TPE plastics.
