Please review the profile. ◯ Ernie Ball Super Slinky, 4 packs I've opened them for inspection because they often have rust. The ones with tape on the back should be usable. The other two have rust on the 9th string, but it's not visible in the image. The ones in the old case have rust on 3 thin strings. There is rust in places other than those shown in the images. I cannot determine whether they are usable as strings. ◯ Strap locks, plastic, black, 4 pieces Many scratches, stains, and distortions. Many of them do not rotate smoothly. I have confirmed that all of them rotate, even if they are stiff. Some are very stiff. Please understand that these are junk items due to their poor condition. I would like to sell them as a set. If there are any defects in the contents other than what is described in the description, please contact me via transaction message before giving a rating. The outer box has dirt, tears, and dents.
