The Four Materials, Compared

Almost every custom case order falls into one of four materials. Each does a different job, and the price gap between them is real.

Microfiber pouch. The lightest and cheapest option at $0.50–1.00 per unit. It is a soft cloth sleeve that protects against dust and light scuffs, and it doubles as a cleaning cloth, which customers actually keep. It offers no structural protection — drop a pair in a microfiber pouch and the frame can still bend — so it is best for low-cost frames, as a secondary layer inside a box, or as a low-budget branded giveaway.

EVA case. The workhorse at $1.50–3.00. EVA (ethylene-vinyl acetate) is a foam-like material that is molded into a shell, usually with a soft inner lining and a zipper. It is lightweight, semi-rigid, and offers real protection against crushing and everyday knocks. For the majority of retail frames — the $25–60 range — EVA is the sweet spot: enough protection to matter, not so expensive that it eats the margin.

PU leather case. The premium look at $2.00–4.50. PU (polyurethane) leather is a synthetic that mimics real leather, and it takes embossing, debossing and stitching beautifully, which is why it is the go-to for brands that want a luxury unboxing at a realistic cost. It is usually stiffer than EVA and pairs well with a microfiber-lined interior.

Hard shell case. The maximum protection at $3.00–6.00. A hard shell — molded plastic, metal, or a rigid composite — will not crush under a backpack or a suitcase. It is heavier and more expensive, so it is reserved for the frames that justify it: high-end acetate, metal frames, polarized or prescription eyewear, and designer SKUs where the case is part of the product story.

Matching the Case to the Frame Value

The mistake I see most often is a mismatch: a beautiful $1.50 EVA case around a $200 frame, or a $5 hard shell around a $9 promotional pair that is going to be given away at a trade show. Neither is wrong in isolation, but both waste money or undermine the product.

Here is the rule of thumb I give buyers. A frame under $15 does not need structural protection — a microfiber pouch or a simple sleeve is proportionate. A frame in the $25–60 range wants an EVA case; that is where the protection-to-cost ratio is best. A frame in the $60–150 range wants PU leather or a well-structured EVA case with a soft lining, because at that price the customer expects the unboxing to feel considered. And a frame above $150 wants a hard shell, or a structured EVA case with an internal frame rest that holds the temples so the frame cannot slide and scratch.

One detail worth specifying regardless of material: the internal structure. A case is only as protective as the way the frame sits inside it. A loose frame in a rigid case can still scratch; a soft case with a firm internal rest often protects better than a fancy case with none. Ask any supplier how the frame is held in place, not just what the case is made of.

Decoration Methods & What They Cost

Decoration is where brands most often overpay or underdeliver. The method should match the material and the price point.

Screen printing. The cheapest and most common, best for one or two colors on microfiber and EVA. It is fast, durable enough for everyday use, and the right default for most orders.

Heat transfer. Allows full-color and photographic detail, useful when your logo has gradients or fine detail. It costs a little more than screen printing and is less abrasion-resistant, so reserve it for soft materials and lower-wear applications.

Embossing and debossing. A heated die presses the logo into PU leather or a structured case, raising it (emboss) or sinking it (deboss). It lasts, it reads as premium, and it is worth the extra cost on a mid-to-high SKU. On a low-cost EVA case it is often not available or not worth it.

Metal plate, gold stamping and stitching. The premium tier. A small metal plate, metallic foil stamping, or contrast stitching signals a high-end product, and it is best reserved for the top of your range — the same frames that justify a hard shell or PU leather case.

The Spec Sheet for a Case Order

Like any factory order, a case is only as good as the spec you write. Five lines do most of the work.

• Material and construction. Name the material (EVA, PU, hard shell, microfiber), the shell rigidity, and the internal structure — does the frame sit in a rest, or loose in the case?
• Interior lining. Soft microfiber, velvet or fabric, and its color. The lining touches the frame, so specify it, do not leave it to chance.
• Closure. Zipper (YKK or equivalent), magnetic flap, or snap. The zipper is the most common failure point; ask for the brand and the pull.
• Decoration. Method, logo artwork in vector, and color (a Pantone reference, not “black”).
• Approved sample. A physical pre-production case with your decoration applied, approved and sealed by both sides before the run.

The rule is the same as for frames: if it is not on the spec sheet, you did not order it, and a case you never approved is a case you cannot complain about.

MOQ & Lead Times

Custom cases usually start around 500 pieces, because the shell, lining and print setup are prepared for your order. Use a stock case shape and customize only the decoration and the MOQ can drop to 100–300 pieces, because the tooling already exists. This is the same trade-off as sunglasses: the more the item is truly yours, the higher the minimum.

Lead time follows the decoration and the material. A stock case with a screen print runs 2–3 weeks; a custom EVA or PU case with an embossed logo runs 3–5 weeks; a fully custom hard shell can run 5–8 weeks once you include mold making and sampling. Summer and the pre-holiday season are the peak, so add a week or two if you are ordering into Q3–Q4.

The practical advice: if you are launching a new brand, order a modest run of a stock case with your logo first. You will learn what your customers value, and you will avoid paying for a custom case mold before you know the frame sells.
