This is a set of 5N pure silver lead wires and screws/washers for cartridges. The 5N pure silver lead wires were sold as such and have been used only once for auditioning, for a single song, so they are practically unused. Regarding shipping, delivery on Saturdays, Sundays, and holidays is currently unavailable, and delivery times have been extended by 1-2 days or more, so it often takes longer. If you are in a hurry, please choose a different shipping method. Important Notes: ★ Due to shipping constraints, the lead wires will be shipped only in a zip-lock bag. If you require damage insurance, please notify us before purchase, as additional shipping charges will apply. ★ The terminals of lead wires often use phosphor bronze or other copper alloys because they are too soft if made of ordinary soft copper, which can cause poor contact during use. Therefore, avoid forcing them in too hard, as this can easily break them off at the base. (Compared to copper, they are harder and less ductile, making them more prone to breaking from impact.) Use needle-nose pliers to gently insert the terminals, gripping the flat part of the tip or the flat part near the insertion point. The hole diameters at both ends of standard lead wires differ even when unused. Cartridges and headshells also have different diameters depending on the manufacturer, so be careful as you may break them during installation. If it's too tight, widen the hole slightly before inserting. We have checked them thoroughly, but the terminals are harder than copper, so it is unlikely that they will break or deform during normal shipping. We tested them by dropping them and stepping on them with shoes, and they are usually fine unless intentionally damaged. Very rarely, there are cases where they are reported to be broken or deformed upon arrival, but as stated in my profile, if you require insurance, you will need to pay additional shipping costs, so please inform us of a shipping method change. If you do not make a request, we are very sorry, but we cannot provide any guarantee. #MC Cartridge MC Cartridge #Step-up Transformer Step-up Transformer #Turntable Turntable #Analog Record Analog Record #Cartridge Record #Tonearm Cartridge #Record Phono Equalizer #Phono Equalizer Tonearm #Audio Audio #Headshell #Lead Wires
