Eager to bypass every difficulty a packer might encounter at their workstation, the design of the “J” shaped Thermos wedge makes it easy to insert on the sharp, cutting edge of the thermos glass. By inserting the short side of the J first, all that remains is to slide the long side to finish positioning the J-Guard correctly. Normally offered in three thicknesses, our J-Guard offers you an ecological alternative to the famous U of foam. You can fix it with the strap or the plastic wrap.
