180 mmの鉛筆、三角グリップペン、150 mmの定規に合わせて設計された新しいEVAペンケース。EN 71試験と学校向け購入者への500個最小ロット。

The pencil case that went into tooling this season started from a 180 mm unsharpened pencil, a 150 mm ruler, a triangular grip pen and a 30 mm eraser, laid out on the sample bench in the order a nine-year-old actually reaches for them. That sounds obvious. Most cases on the market are designed as a rectangle first and then the contents are made to fit inside it.

We build these at Shore C 45-55 with a 3-4 mm wall, light enough that a full case still sits under 200 g. The shell stands up on a desk instead of flopping, which is the single most requested feature in feedback from Japanese buyers, and a half-open lid stays put rather than snapping shut on fingers.

## Built around the contents

Triangular pen barrels need a slot with a V profile or they roll and jam against the zipper. Rulers want a flat full-width pocket rather than a narrow one, because a 150 mm ruler in a 140 mm pocket curls. Erasers and small sharpeners go into a separate elasticated mesh pocket so eraser dust does not migrate onto pen bodies. Internal clearance is held to around +/-1 mm on the pen slots, and the lid lining is flat rather than egg-crate so nothing catches when the case is closed in a hurry.

## Where EVA beats a fabric pouch

A fabric pencil pouch costs less and packs flatter, so we still make them in Oxford for buyers who want a soft option. The failure mode is crush: a pouch in a backpack under a textbook bends pencil leads and snaps the point off a mechanical pencil. A molded shell takes that load around the contents instead of through them. It is also washable, which matters after a pen leaks. The weight difference between the two at the same capacity is roughly 60-90 g, and the EVA version is about 12-15% bulkier in a bag.

## Customization for school and promo buyers

Print, woven label, zipper puller colour and interior lining colour all change without tooling. Minimums start at 500 pieces, quoted at 500, 1,000 and 3,000, and samples come off the bench in about three days for a standard shape. Children's versions are tested against EN 71 for the EU and carry California Prop 65 wording for the US, with RoHS and REACH declarations as standard. Zippers cycle to roughly 5,000 opens, which is around three school terms of daily use, and YKK or an equivalent is specified so a replacement run matches the original puller.

Buyers pairing cases with bags usually look at the [EVA backpack line](https://evacasemanufacturer.com/ja/products/sub/eva-backpack-cases) alongside the [EVA pencil case range](https://evacasemanufacturer.com/ja/products/sub/eva-pencil-case), because a matching shell and lining reads as a set on a shelf. Full trim options sit in the [customization program](https://evacasemanufacturer.com/ja/customization). The first bulk run off the new tooling went to a stationery chain in Yokohama, and their only change request was a darker lining that would not show pen marks.

## FAQ

**What MOQ does LIANPING require for custom EVA pencil cases?**

Minimum order is 500 pieces, with tier pricing at 500, 1,000 and 3,000. Print, woven labels, zipper puller colour and lining colour do not require new tooling, so they can be mixed within a tier. A change to shell geometry or cavity layout does require new tooling.

**How long does an EVA pencil case sample take?**

About three days for a standard compression molded shape with standard slots. Sampling starts from the actual stationery items or a dimensioned drawing, because slot depth and width are cut to the real pen, ruler and eraser rather than to nominal sizes. First approval usually includes a lid closure and zipper check.

**Are LIANPING pencil cases safe for children and compliant for EU and US import?**

Children's versions are tested against EN 71 for EU sales and carry California Prop 65 wording for the US, with RoHS and REACH declarations supplied as standard. Adhesive selection is part of sample approval because odour is closely checked in this category, and zippers are cycled to about 5,000 opens.
