What company or brand do you use for your shrink caps? I have been working through a 1000 lot of heat shrink sleeves from morewinemaking.com and need to purchase some more. However these are very cheap. They shrink well with boiling water and OK with a heat gun (a few wrinkles). To remove them they spiral off in 3-5 different pieces and are not like commercial quality ones that can spiral off in one piece and are thicker. If you pull the small pull tab on them it just rips off a tiny piece and you have to cut the remaining cap off with a knife which still comes off in pieces. Any suggestions for better quality ones?
