The Collectors Edition calls from Big Sean are one of a kind and a true call collectors dream. Sean turns each call on a single piece hand lathe from exotic, high quality woods. The calls are all hand sanded, hand polished, and finished with a thick high gloss sealer. Big Sean spends several hours on each call and personally makes each call per order as they come in. This is not a high volume manufacturing process. We always produce the highest quality products in the industry. Each call has a stainless steel o-ring insert for your personal choice of guts. 100 percent satisfaction guaranteed. Made in the USA.
