◆ Large sponge polishing pads (15cm diameter) Set of 4 for base preparation, alternative to Abralon (Slight discoloration on the edges) ① P180 (Equivalent to Abralon #100) ② P400 (Equivalent to Abralon #250-300) ③ P500-600 (Equivalent to Abralon #300-400) ④ P800-1000 (Equivalent to Abralon #500-600) For bowling ball polishing ---------------------- ◆ While Abralon is very soft and pliable, these have a firmer sponge and abrasive surface. They are not suitable for car polishing, but are perfectly usable for bowling balls. The grit feels about two grades coarser than Abralon. ◆ If you're doing base preparation, this is the only choice. Abralon is unnecessary for base preparation. ---------------------- Approximate delivery time after shipping (Using Japan Post) Kanto: 1-3 days Honshu: 2-4 days Kyushu / Hokkaido / Islands: 3-5 days Okinawa: 4-7 days
