Set of 6 pre-treated empty cans (mackerel cans), ready for your projects. Size per can: Approximately 5cm high, 7.5cm in diameter. You can create upcycled cans by painting them with your favorite paints! Rust-resistant coating applied, so you can enjoy your creations for a long time. Also, the inner rim has been removed to prevent injury. Furthermore, this rim often traps dirt that cannot be removed with regular washing, so removing it makes the cans more sanitary and eliminates concerns about lingering odors. There are can openers that completely remove the rim, but that looks less appealing, so we've removed only the top rim, leaving a small rim. Holes have been pre-drilled, but there may be some burrs near the holes (some have been removed). Please note that the hole diameters are irregular (4-5mm). The rust prevention coating is "Power Tech," applied twice. There may be some stickiness if stacked vertically. ■ No price negotiations. Anonymous and same-day shipping available (however, shipping is not possible on rainy days or between approximately 4 pm and the morning). Shipped via Yu-Packet Plus. Packaging materials may be reused. Please understand.
