Great for tree cores
Derek from Davis, CA – Verified Buyer
Have used these for storing tree cores during field collection. They work great and allow the cores to dry without molding. This model fits both 4.3mm and 5.15 mm cores. 5.15mm cores are a bit tight, but it's easy to push them out of the straw with another core. 4.3mm cores can be shaken out. Easy to seal the straws by bending back on themselves--no need for tape.
