Snow Peak Limited Edition Sierra Cup Holders (2), I believe it was over 10 years ago, I had them stored in the warehouse without using them. I've forgotten whether it was an event prize or a purchase bonus, but I think it's a limited edition item not in the catalog. ★ It's a Sierra cup holder exclusively for Snow Peak's LV-51/Folding D Chair AL and LV-51P/Pad-in Chair AL. Please do not attach it to any other chairs. ★ It's exclusively for Snow Peak's E-103 Sierra Cup and E-104 Titanium Sierra Cup. Product price (2 pieces) ¥2,800, shipping ¥475, total ¥3,275.
