This item is new and unopened. - Brand: TSUKURIRO Bottom Studs, Round, 10mm - Quantity: 10 - Color: Gold Thank you for viewing.

TSUKURIRO Bottom Studs, Round, 10mm, Screws, Bags, Repairs, Leathercraft, DIY, Handmade Parts This is a set of hemispherical bottom studs. Size: Contact surface diameter 10mm, Height 5mm, Weight: 2g/piece. These are the type that are attached with screws, and you tighten them with a Phillips screwdriver. When you tighten the screws, a gap of about 3mm will be created, so you may need to prepare a bottom plate depending on how you use them. How about using them to protect the bottom of your bags or to arrange their appearance? ⚠ To take the photos, I opened a separate bag of the same product. The item you will receive is unopened, so please rest assured.
